Pro Vis de construction « Grade Heavy Duty » n° 14 x 1 Inch , tête Torx Star, rondelle de renfort modifiée, compatibles avec le bois traité Acq, en acier traité thermiquement, boîte de 100 Piece , fixations structurelles robustes, approuvées par Crew
This set includes 100 pro-grade number 14 lag screws built for connecting heavy lumber to solid structural supports without bending. Designed for exterior applications, these threaded fasteners anchor into pressure-treated or ACQ lumber where moisture resistance matters, making them ideal for framing joists, securing beams, and assembling deck frameworks that stand up to seasonal shifts.
✅ Heat treated steel core resists bending under high shear loads ✅ Triple coat barrier protects bronze surface against ACQ rot treatments ✅ Modified truss washer head spreads pressure for flush secure mounts ✅ Wood screw thread design pulls deep into lumber requiring less driving torque ✅ Torx star drive slot engages fully to reduce bit cam-out and strip risks💡 How does choosing ACQ compatible lag screws help prevent chemical attacks on treated pine and spruce structural connections?
Plain steel bolts corrode quickly when exposed to copper-based treatment salts that leach out as wood ages and weathers outside.
Using a corrosion-rated finish creates a shield that stops rust bleeds from ruining stained decks and hides fastener heads behind trim caps nicely.
Grabbing the right gauge prevents stripped drives when wrestling thick timber together, saving contractors hours of pulling failed anchors back out of rotten spots during teardown work.
- Verifying screw compatibility avoids costly callbacks by ensuring metal lasts longer than the wood being joined.
- Torx drivers reduce downtime on site since bits stay locked tighter instead of spinning loose under heavy load.
- Heat hardening boosts pull-through resistance so joists and beams stay rigid even when shifting ground settles foundations.
