S-93406A243 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications.
• Enhanced load distribution and vibration resistance from the wide truss head design, reducing the risk of material damage.
• Efficient, self-tapping installation using thread forming (Type A/AB) for strong, reliable threads in sheet metal without pre-tapping.
• Secure, high-torque driving with the No. 2 Phillips drive, minimizing cam-out and speeding up assembly.
• Full-length threading ensures maximum grip and holding power along the entire 1/2" length for sturdy fastening.
• Precision compatibility with a No. 21 (0.159") drill bit, simplifying hole preparation and ensuring a tight fit.
• Compliance with RoHS 3 and REACH regulations guarantees safety and environmental responsibility for industrial use.

Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, these 316 stainless steel tapping screws address common industrial challenges like corrosion, vibration loosening, and installation efficiency. The thread forming design creates precise, durable threads in materials up to 0.025" thick, eliminating the need for separate tapping operations and reducing assembly time. The Phillips truss head offers a low-profile, wide bearing surface that distributes clamping force evenly, preventing pull-through in thin sheets and enhancing joint integrity. With fully threaded shanks and a pointed tip, these screws provide consistent engagement and reliable performance in HVAC, automotive, and electronics enclosures, ensuring long-term reliability even in corrosive or high-moisture environments.

Specification Summary & Compliance

This No. 10-12 x 1/2" tapping screw features a right-hand thread with approximately 12 threads per inch and a rounded truss head (0.448" diameter). Manufactured to standard thread forming (Type A/AB) specifications, it ensures precise fit and high pull-out strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent environmental and safety standards for industrial components.
