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

Description

Fast Big Dog (dimension 10x140 mm) is a strong, high-performance and partially threaded construction screw for outdoor use that advantageously replaces traditional French wood screws in load-bearing wood-to-wood constructions. The screw is specially designed for demanding outdoor installations and combines cutter tip, stem cutter and an integrated large washer head. This design guarantees exceptionally high penetration values while minimizing the risk of cracking in the wood.

Benefits and Features of Big Dog 10x140 mm

• Replaces French wood screw: Provides significantly faster fastening and superior clamping force without the need to use a separate washer or pre-drill in most standard timber.
• Large integrated washer head: Creates significantly higher pull-through values, which is a decisive advantage when dimensioning and calculating load-bearing wood-to-wood structures with partially threaded screws.
• Cutter tip & stem cutter: The cutting cutter tip provides an immediate grip in the timber. The integrated stem cutter (standard on all screw lengths over 50 mm) reduces the tightening torque and makes installation considerably easier with long screw lengths.
• Corrosivity class C4 (ZFmax): Advanced ZFmax surface treatment developed for tough Nordic outdoor environments with high humidity and moderate salt content.
• Documented safety & quality: The screw is fully CE-marked according to the standard EN 14592 and has type approval certificate SITAC 0044/07.
• TX groove (T40): Equipped with TX mount (Torx T40) that guarantees optimal power transmission and minimizes the risk of cam-out when tightening hard.

Areas of application

Fast Big Dog 10x140 mm is specifically designed for rough wooden structures outdoors where the highest possible demands are placed on clamping force, load-bearing capacity and strength:

• Load-bearing joists, load-bearing cables and roof trusses in wooden frames and joists.
• Anchoring of posts and load-bearing frames in balcony, decking and terrace construction.
• Wood-to-wood assembly where structural calculations require a partially threaded screw with documented high pull-through values.
