Processing & Customization
Each screw undergoes a thorough heat treatment process to achieve the required case hardness (HRC 52-56) on the drill point, enabling the screw to penetrate steel substrates up to 12mm thick. To guarantee corrosion resistance, we offer surface finishing options including zinc plated (clear, yellow, or black) and geometric (Dacromet) coatings.
We provide comprehensive customization services, including tailored lengths, specific coating requirements to meet stringent salt spray test standards, and private-label packaging to align with your brand identity.
Customer Needs & Pain Points
Pain Point: Contractors often face "burn-out" or broken tips when fastening into heavy-gauge steel, leading to downtime and material waste.
Solution: The C1022A material combined with optimized heat treatment ensures the drill point penetrates hard substrates efficiently without fracturing, significantly reducing installation failure rates.
Pain Point: Traditional hex heads often cam out or strip in tight spaces, and small heads can pull through thin sheet metal.
Solution: The Phillips Truss Head provides a broad bearing surface that distributes clamping pressure evenly, preventing pull-through in soft metals or plastics. The Phillips drive offers reliable bit engagement for consistent seating.
Pain Point: Corrosion in outdoor or humid environments leads to premature fastener failure.
Solution: With customizable high-corrosion-resistant coatings, we ensure long-term durability that matches the lifecycle of the structural components.
