Wood Screw Big Dog 10x140mm C4 ZF Max 25pcs Fast 281538

Description

Strong construction screw for outdoor use that effectively replaces traditional French wood screws for load-bearing wood-to-wood constructions. Fast Big Dog (dimension 10x140 mm) is a high-performance, partially threaded wood screw designed for demanding outdoor mounting. The screw combines a cutter tip, stem cutter and an integrated large washer head, which provides exceptionally high penetration values and minimizes the risk of cracking.

Benefits and Features

• Replaces French wood screws: Provides faster fastening and superior clamping force without the need for a separate washer or pre-drilling in most standard timber.
• Large washer head: Creates significantly higher pull-through values, which is particularly crucial when dimensioning and calculating load-bearing wood-to-wood structures with partially threaded screws.
• Cutter tip & stem cutter: Cutting tip provides direct grip in the wood. The integrated stem cutter (standard on all screw lengths > 50 mm) reduces the tightening torque and makes installation considerably easier.
• Corrosion class C4 (ZFmax): Advanced surface treatment developed for tough outdoor environments with high humidity and moderate salt content.
• Documented safety: The screw is CE marked according to standard EN14592 and has type approval certificate SITAC 0044/07.
• TX groove (T40): Guarantees optimal power transmission and reduces the risk of cam-out.

Areas of application

Fast Big Dog 10x140 mm is designed for rough wooden structures outdoors where high demands are placed on clamping force and strength:

• Load-bearing joists, support lines and roof trusses in wooden frames.
• Anchoring of posts and joists in patio and terrace construction.
• Wood-to-wood assembly where structural calculations require partially threaded screws with high pull-through values.
