S-90415A435 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability with integrated No. 3 drill tip eliminates pre-drilling steps, saving labor time and reducing installation costs in steel and sheet metal assemblies.
• Superior corrosion resistance from 18-8 stainless steel coating ensures long-term reliability in harsh environments, minimizing maintenance and replacement frequency.
• Optimized thread forming design creates strong, permanent threads in base materials for enhanced pull-out resistance and vibration-proof fastening.
• Phillips pan head drive provides secure tool engagement and a low-profile finish that sits flush against surfaces without snagging.
• Full threading along 1" length maximizes grip range and distribution of clamping force across the entire fastened joint.
• Industry-compliant manufacturing meets RoHS 3 and REACH standards for safe, environmentally responsible use in global supply chains.
• 0.126" maximum drilling thickness enables efficient penetration through multiple material layers with consistent performance.

Professional Applications & Engineering Value

This No. 8-18 x 1" Phillips pan head tapping screw delivers exceptional value in industrial fastening by combining material durability with functional efficiency. The corrosion-resistant 18-8 stainless steel construction resists oxidation and chemical exposure, making it ideal for outdoor equipment, HVAC systems, and marine applications. Its thread forming (BSD) design displaces material rather than cutting it, resulting in tighter thread engagement and reduced risk of loosening under dynamic loads. The integrated No. 3 drill tip penetrates up to 0.126" of steel, stainless steel, and sheet metal without pilot holes, streamlining assembly lines and reducing tooling requirements. Fully threaded for uniform stress distribution, this screw solves common challenges in construction and manufacturing where speed, strength, and corrosion protection are critical.

Specification Summary & Compliance

Manufactured to precise inch measurements with No. 8-18 UNC thread and Class 2A tolerance for consistent fit. The BSD tapping screw type follows standard thread forming principles for reliable performance in metal substrates. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
