S-90054A410 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ideal for harsh industrial environments
• Enhanced holding power from the 0.676" flange diameter, preventing pull-through in sheet metal
• Quick and secure installation with external hex/slotted drive for easy tool engagement and torque application
• Reliable thread-forming capability with A/AB type and pointed tip, eliminating the need for pre-tapping in materials up to 0.025" thickness
• Consistent fastening performance thanks to 10 TPI precision threading and fully threaded 3/4" length
• Compliance with global standards including RoHS 3 and REACH, ensuring safe and sustainable use
• Durable hex head design (1/2" width) for high-torque applications and reduced stripping risk

Professional Applications & Engineering Value

These 5/16" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, where vibration resistance and material integrity are critical. The thread-forming design creates strong, permanent threads in thin materials without requiring pre-drilled holes, reducing assembly time and labor costs. The external hex head combined with a slotted drive offers versatility for both power and manual tools, while the flanged design distributes clamping force evenly to prevent sheet deformation. Made from zinc-plated steel, these 10 TPI fasteners provide excellent durability in automotive, HVAC, and electrical enclosure applications, ensuring long-term reliability under mechanical stress and environmental exposure.

Specification Summary & Compliance

These screws feature a 0.313" thread diameter with 10 TPI threading and are fully threaded for consistent engagement. The hex head measures 1/2" in width and 0.285" in height, designed for standard tool compatibility. Manufactured to A/AB tapping screw type standards with a pointed tip and right-hand thread direction, they are suitable for use with a 6.9 mm (0.2717") drill bit in materials up to 0.025" thickness. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
