S-95015A315 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Enhanced security and tamper resistance with T30 Torx drive to prevent unauthorized removal
• Strong, reliable thread forming creates durable threads in sheet metal for superior vibration resistance and holding power
• Flush, low-profile installation with standard flat head and 82° countersink angle for a smooth, finished surface
• Simplified installation process with compatibility for standard 5.5 mm (0.2165") drill bits and clear 0.025" maximum drilling thickness guidance
• Full-length threading ensures maximum grip and consistent fastening strength along the entire 1-1/4" length
• Precision manufacturing with tight head diameter tolerance (±0.005") for consistent performance and fit

Professional Applications & Engineering Value

This 1/4"-10 T30 flat head tapping screw is engineered to solve critical challenges in sheet metal fabrication and assembly. The thread forming (Type AB) technology displaces material rather than cutting it, creating stronger, more vibration-resistant threads that won't loosen under stress. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance, making it ideal for outdoor enclosures, HVAC systems, and electrical cabinets. The combination of the tamper-resistant Torx drive and flat head profile with an 82° countersink ensures both security and a flush finish, eliminating snag points and providing a professional appearance. This design is particularly valuable in applications where disassembly should be controlled, such as in public infrastructure or secured industrial equipment.

Specification Summary & Compliance

This screw conforms to standard inch system specifications, including a 1/4" thread diameter with 10 threads per inch and a right-hand thread direction. It is fully threaded and features a standard flat head with precise manufacturing tolerances. The screw is designed as a Type AB thread forming tapping screw for use in sheet metal and is compatible with a 5.5 mm (0.2165") drill bit. The 18-8 stainless steel material complies with RoHS and REACH environmental standards, ensuring it is free from hazardous substances and suitable for various industrial applications.
