S-94058A127 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Self-drilling capability with integrated 1/4" drill tip eliminates pre-drilling, saving labor time and costs
• Reliable sealing performance through integrated stainless steel/rubber washer that prevents moisture ingress and leakage
• High-strength thread forming creates permanent, vibration-resistant threads in stainless steel and sheet metal up to 0.15" thick
• Easy installation with external hex drive design allowing high torque application and secure fastening
• Full threading ensures maximum grip length and uniform load distribution across the entire fastener
• Regulatory compliance meets RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 10-16 thread forming screws deliver exceptional value in industrial applications where stainless steel and sheet metal assemblies require both structural integrity and environmental protection. The zinc-plated 410 stainless steel construction provides excellent corrosion resistance, while the integrated drill tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs. The thread forming design creates stronger, more durable threads than conventional cutting screws, making them ideal for applications subject to vibration and thermal cycling. The combination of stainless steel/rubber washer ensures reliable sealing against moisture and contaminants, protecting sensitive components in outdoor equipment, HVAC systems, and electrical enclosures.
