Carbon Steel Wood Screws
Product Overview
16-10×65-105 T40 Washer Head Torx Grass Rope Screw is a heavy‑duty fastening screw specifically for timber structures, made of high‑strength carbon steel substrate with a zinc‑nickel alloy anti‑corrosion surface treatment. The #16 thick shank with 10 TPI coarse thread is available in multiple lengths from 65 to 105 mm, featuring an integral washer flange head with T40 Torx drive recess, and a wood‑use sharp‑pointed grass rope thread that can directly tap into wood, combining high load‑bearing capacity with long‑term outdoor rust protection.
Product Applications
Timber Structure Engineering: Fixing load‑bearing structures such as cabin joists, glued‑laminated main beams, roof timber frames, etc.
Outdoor Landscaping: Outdoor wood components such as preservative‑treated timber boardwalks, courtyard platforms, pavilions, hardwood railings, etc.
Steel‑Timber Composites: Assembly of light‑gauge steel with wood joists, steel‑wood furniture, and heavy‑duty storage timber racks.
Coastal High‑humidity Scenarios: Seaside boardwalks, coastal garden facilities, with long‑term rust resistance, reducing maintenance.
Heavy Solid Wood Furniture: Load‑bearing splicing of log beams, large solid wood cabinets, bed frames, etc.
Product Features
Heavy‑duty Thread Design: 16# thick shank with 10 TPI coarse thread, deep engagement, strong pull‑out and shear resistance, multiple lengths suitable for various thick wood components.
Integral Washer Head: Built‑in widened flange washer, eliminating the need for extra washers, compresses without splitting the wood surface, provides sealing and waterproofing, and ensures efficient installation.
T40 Torx Recess: Six‑point force distribution handles high torque, resists stripping and cam‑out, enables quick project installation, and offers anti‑tamper benefits.
High‑strength Anti‑rust Combination: Carbon steel quenched for both toughness and hardness, resists breakage and bending in hardwoods; zinc‑nickel plating provides salt spray resistance, suitable for humid and coastal environments, reducing the risk of hydrogen embrittlement.
Self‑tapping Sharp‑pointed Thread: Wood‑specific cutting thread, eliminates pre‑drilling, can be directly driven into various solid woods and engineered panels.
