Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 - ETA-Approved Chipboard Screws For Timber Work

Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 brings a 4 mm x 40 mm fully threaded, TX20-driven chipboard screw in a 200-piece box for demanding timber connections. For structural wood projects, its ETA approval and blue passivated zinc coating matter most.

Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 is a 4 mm x 40 mm chipboard screw pack with 200 fully threaded screws designed for reliable timber and panel connections in construction and DIY projects. The screws combine a countersunk head with TX20 star drive, blue passivated zinc plating, and European Technical Assessment approval for use in structural wood applications, giving tradespeople and serious DIYers a standardized fastener for everyday jobs in softwood, hardwood, and engineered wood.

Design, Dimensions And Materials

The core of the Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 concept is the combination of a compact screw size and a construction-focused geometry. On the official technical page, Fischer specifies a diameter of 4 mm and a length of 40 mm for this model, with a thread length of 35 mm that runs almost the entire shank for better load transfer in wood joints.Fischer lists these dimensions directly for the FPF II CTF 4.0 x 40 BC 200 variant. The screw uses a countersunk head, allowing it to sit flush in timber surfaces once driven, and a TX20 internal star drive that supports high torque transfer without stripping in professional impact drivers.

In terms of material and finish, Fischer describes the FPF II CTF BC screws as made from hardened steel with a blue passivated, galvanically zinc-plated coating.The data sheet calls out hardened steel and blue passivated zinc plating for corrosion protection. Under-head milling ribs and a fully threaded shank are part of the PowerFast II geometry, helping the screw bite quickly into wood and distribute loads evenly along the joint.

Application Scope And ETA Approval

Fischer positions the PowerFast FPF II CTF 4.0 x 40 BC 200 as a chipboard screw that is suitable not only for standard panel work but also for structural wood connections when used within its approval. On the product page, the company notes that PowerFast II screws are approved for use with Fischer plugs such as DuoPower and UX at recommended loads, and for fastening general wood connections, claddings, baseboards, and metal fittings onto timber substrates.Fischer highlights suitability for structural timber connections with ETA-listed loads when combined with specific plugs and constructions. That makes the FPF II CTF 4.0 x 40 BC 200 attractive in projects where chipboard screws must satisfy design codes and documentation rather than informal DIY use alone.

Beyond plug applications, the PowerFast II family is described on Fischer’s international site as a high-performance solution for timber construction, offering variants that cover glued-laminated timber, cross-laminated timber panels, oriented strand boards, and solid structural timber.The PowerFast II overview describes the series as powerful wood construction screws for timber construction with multiple head and drive options. Although the FPF II CTF 4.0 x 40 BC 200 sits in the chipboard screw subcategory, the same geometry and approvals are leveraged for timber engineering, giving a small, 40 mm screw a structured place in larger assemblies like sheathing, decking edges, and fixture mounting.

Packaging, Piece Count And International Positioning

Fischer’s specification lists the PowerFast FPF II CTF 4.0 x 40 BC 200 pack as a folding box variant with a quantity of 200 screws.The product data explicitly notes a folding box packaging format and a count of 200 pieces. The GTIN 4048962370171 ties this model into distribution catalogs and retail systems, helping builders and distributors standardize ordering in multi-country environments.

Within the broader PowerFast portfolio, this screw sits alongside stainless A2 and A4 variants and part-thread models that target more corrosion-prone or load-critical installations.Another related 4.0 x 40 mm pack, the FPF-SZ 4.0 x 40 A2P 200, uses A2 stainless steel with a partial thread and PZ drive for higher corrosion resistance. Compared with these stainless options, the 4.0 x 40 BC 200 zinc-plated screw pack focuses on general indoor or protected outdoor work where a hardened steel core and zinc coating provide sufficient protection at a lower material cost than stainless.

Brand, Manufacturer And US Presence

PowerFast screws are part of Fischer’s global fastening portfolio, produced by Fischerwerke GmbH & Co. KG, the German family-owned manufacturer known for its plugs and fastening systems.Independent background sources describe Fischerwerke as a multinational manufacturer specializing in fastening products for construction and DIY markets. The PowerFast and PowerFast II lines sit alongside wood construction screws and plug systems, with a focus on combining standardized geometry, ETA approvals and materials suitable for structural timber engineering.

For North American buyers, Fischer operates through several entities. A contact page lists Fischer USA Stainless Steel Inc. at 1120 AEDC Access Rd in Manchester, Tennessee as a key United States presence for stainless steel and fastening solutions.The Fischer USA Stainless Steel Inc. contact page provides the Tennessee address and phone contacts for US operations. While detailed US retail listings for the exact FPF II CTF 4.0 x 40 BC 200 pack are scarce, the PowerFast brand and comparable 4 mm x 40 mm, 200-piece packs appear in English-language trade catalogs and retailer sites in Europe and other markets, indicating that US professionals encountering Fischer fasteners can expect similar geometry and approvals even if exact packaging codes differ between regions.

Comparison With Stainless A2 PowerFast 4.0 x 40

One direct comparison within Fischer’s own catalog is against the A2 stainless PowerFast FPF-SZ 4.0 x 40 A2P 200 pack. This stainless variant uses the same 4 mm diameter and 40 mm length but switches to a partial thread instead of the full thread used on the FPF II CTF 4.0 x 40 BC 200, and combines that with an A2 stainless material and PZ drive.Fischer lists the stainless FPF-SZ 4.0 x 40 A2P 200 as a 4 mm x 40 mm screw with partial thread, PZ2 drive, A2 material and a 24 mm thread length. That shorter 24 mm thread length, compared with the 35 mm thread length on the zinc-plated PowerFast II CTF screw, shifts how loads are carried in the joint—partial thread screws often draw two timber members tightly together, while full thread screws emphasize holding power along the entire penetration depth.

For applications, Fischer positions the stainless PowerFast A2 screw as a premium option for carports, balconies and other exposed structural connections where stainless material is needed to resist corrosion over long service lives.The application notes mention balcony and carport fixings as typical uses for the A2 stainless PowerFast version. In contrast, the FPF II CTF 4.0 x 40 BC 200 pack offers a hardened steel, zinc-plated solution well suited to interior or protected exterior wood joints, panel mounting and general fixtures, where the emphasis is on fast driving behavior and strong holding power with ETA-listed loads rather than extreme corrosion resistance.

Positioning In Timber Fastening Practice

In timber construction practice, a 4 mm x 40 mm fully threaded chipboard screw like Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 fills a specific niche: fastening sheathing and thinner timber sections, anchoring metal fittings to wood, and securing baseboards or trim pieces without oversizing the fastener. Combined with its countersunk head and TX20 drive, it provides predictable installation torque and flush finishes that matter in both structural and visible applications.

Relative to larger PowerFast II wood construction screws with diameters of 8 mm, 10 mm or 12 mm for heavy timber connections,PowerFast II wood construction screws such as the FPF II HWTF BC line scale up to 8-12 mm diameters for major timber joints, the 4 mm x 40 mm chipboard screw is a lighter-duty but frequently used component. For US-based professionals who already rely on ETA-approved screws in engineered timber projects, the PowerFast II geometry and documentation offer familiarity, even when the exact European packaging codes like 670159 FPF II CTF 4.0 x 40 BC 200 are imported or mirrored by North American distributors under equivalent catalog numbers.

In practical terms, that positions Fischer PowerFast FPF II CTF 4.0 x 40 BC 200 as a solid choice for builders and installers who need many identical, fully threaded screws for repetitive timber and panel fastening tasks, prioritizing driveability, geometry and approval status over decorative features or consumer-facing branding.
