S-92525A420 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Efficient thread forming design (Type B) creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
• Secure Phillips No. 2 drive ensures easy installation with common tools and minimizes cam-out for consistent fastening.
• Full threading and blunt tip provide maximum grip across the entire length and prevent material splitting.
• Optimized for No. 29 drill bits (0.136" diameter), ensuring precise fit and reducing the risk of misalignment in sheet metal applications.
• Durable pan head design offers a low-profile, rounded finish that sits flush and resists snagging.
• Compliant with RoHS 3 and REACH regulations, guaranteeing safe, environmentally responsible materials for global supply chains.

Professional Applications & Engineering Value

These No. 8-18 x 1/4" stainless steel tapping screws are engineered to address common challenges in sheet metal assembly, where vibration resistance, material integrity, and corrosion prevention are critical. The 18-8 stainless steel composition provides excellent strength and rust resistance, making them suitable for outdoor, marine, or high-moisture industrial settings. The thread forming (Type B) design cold-forms mating threads as it's driven, eliminating chips and ensuring a tight, vibration-resistant fit without weakening the base material. With a Phillips pan head and fully threaded shank, these screws deliver uniform clamping force and are easy to install in confined spaces, reducing labor costs and improving assembly line efficiency for HVAC, electronics enclosures, and automotive panels.

Specification Summary & Compliance

This screw features a No. 8-18 thread with a 0.164" diameter and 18 threads per inch, adhering to standard inch-series tolerances for consistent performance. The pan head measures 0.322" in diameter and 0.115" in height, designed for a standard profile. It is fully threaded with a right-hand thread direction and blunt tip for controlled penetration. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring the absence of restricted hazardous substances and supporting sustainable manufacturing practices.
