S-90184A154 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine or chemical exposure applications
• Efficient thread-forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs
• Optimized for 0.025" maximum sheet thickness with precise No. 32 drill bit compatibility, ensuring secure fastening in thin metal assemblies
• No. 2 Phillips pan head drive provides reliable torque transfer and a low-profile, rounded finish that resists snagging
• Full 7/8" threading offers maximum grip length and load distribution across the entire fastener engagement
• Compliant with RoHS 3 and REACH regulations for safe use in regulated industries and global market acceptance
• Standardized No. 6-18 thread with right-hand direction ensures compatibility with existing inch-system components and tooling

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver critical performance where corrosion resistance and sheet metal integrity are paramount. The thread forming (Type A/AB) design displaces material rather than cutting it, producing zero chips while creating stronger thread engagement that resists vibrational loosening. This makes them ideal for HVAC ductwork, electronic enclosures, and automotive panels where sealed joints and material strength preservation are essential. The Phillips pan head combines secure drive engagement with a smooth, rounded profile that eliminates sharp edges in finished assemblies. Manufactured to precise inch dimensions with consistent 18 TPI threading, these screws provide reliable performance in high-volume production environments.

Specification Summary & Compliance

This No. 6-18 x 7/8" tapping screw features standard Class 2A thread tolerances with a 0.138" thread diameter and fully threaded shank design. The thread forming tapping method complies with standard industrial specifications for sheet metal fastening applications. Manufacturing and material composition adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory acceptance for industrial distribution.
