S-90315A461 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Enhanced holding power through thread forming technology, creating strong, permanent threads in sheet metal without pre-tapping.
• Streamlined installation with Phillips No. 2 drive and fully threaded design for quick, efficient fastening and reduced assembly time.
• Clean, flush finish thanks to the undercut oval head and 82° countersink angle, providing a smooth surface and professional appearance.
• Precise compatibility with No. 29 drill bits (0.136" diameter), minimizing errors and ensuring optimal performance in sheet metal up to 0.025" thick.
• Wide industrial applicability as Type A/AB tapping screws, designed specifically for sheet metal and other thin materials.
• Regulatory peace of mind with full compliance to RoHS 3 and REACH, meeting strict environmental and safety standards.

Professional Applications & Engineering Value

These No. 8 x 3/8" stainless steel oval head tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and weak thread retention. The 18-8 stainless steel offers excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. Using thread forming technology (Type A/AB), these screws displace material to form tight, secure threads without cutting, which reduces stress concentrations and increases joint integrity. The fully threaded design and Phillips No. 2 drive enable quick installation with standard tools, while the undercut oval head sits flush to prevent snagging and improve aesthetics. Perfect for HVAC, electronics enclosures, and automotive panels, these screws deliver reliable performance where vibration resistance and durability are critical.

Specification Summary & Compliance

This product features a thread diameter of 0.164" with approximately 15 threads per inch, adhering to standard inch measurements for consistent fit. The oval head design includes an 82° countersink angle for seamless integration. Manufactured to meet industry specifications for Type A/AB thread forming tapping screws, it ensures precise threading in applicable materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms adherence to environmental and health regulations, supporting safe use in global industrial supply chains.
