What it is: High-hardness, rust-resistant threaded fasteners designed for reliable, long-lasting hold in both dry and moist environments. Durable material: Made from high-quality material with elevated hardness for strength and wear resistance. Suitable for use in damp or humid conditions without fear of rust. Smooth, precise finish: Burr-free, smooth surfaces reduce slippage during installation and minimize damage to workpieces. The driven head design improves control and makes driving the fastener easier and faster. Engineered threads for grip: Deep, clearly formed threads provide secure engagement, high pull-out resistance and even load distribution for a stable, locked connection. Performance benefits: Improved holding power reduces the risk of loosening under load, while the clean finish and head design speed up installation and reduce tool wobble. Wide compatibility: Ideal for a broad range of materials and settings including household repairs, workshop projects, crafts, furniture assembly and construction tasks. Use scenarios Kitchen or furniture hardware: Fasten cabinet handles, hinges and lock plates securely with deep threads that resist pull-out during everyday use. Marine or outdoor repair: Install or replace fittings on boats or outdoor structures where humidity and exposure demand rust-resistant, high-strength fasteners. Woodworking and carpentry: Secure panels, trim and structural joinery with even force distribution to prevent splitting and ensure long-term stability. Key attributes at a glance Material: high-quality, high-hardness, rust-resistant Finish: smooth and burr-free for safer, easier installation Threading: deep, clear threads for strong hold and high pull-out strength Applications: household, workplace, crafts, handles, locks, furniture, construction, marine, repairs, woodworking and more Reliable, straightforward fastening for projects where strength, corrosion resistance and clean installation matter.
