S-91675A331 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 410 Stainless Steel material, ensuring long-term reliability in harsh industrial environments.
• Superior holding power and vibration resistance through thread forming design, which creates strong, permanent threads in sheet metal without pre-tapping.
• Quick and secure installation with an external hex drive and flanged head, allowing for high torque application and eliminating the need for separate washers.
• Optimized for sheet metal applications with a pointed tip and fully threaded shank, enabling easy starting and consistent fastening in materials up to 0.025" thickness.
• Precise fit and reduced assembly time by compatibility with a No. 29 drill bit (0.136" diameter), ensuring accurate hole sizing for reliable performance.
• Compliance with environmental and safety standards, meeting RoHS 3 and REACH regulations for safe use in global industrial supply chains.

Professional Applications & Engineering Value

These No. 8-15 x 1" hex head tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and loosening under stress. The 410 Stainless Steel construction provides excellent strength and corrosion resistance, ideal for outdoor or corrosive settings. With a thread forming design, these screws displace material to form tight, load-bearing threads, reducing the risk of strip-out and improving joint integrity. The flanged head distributes clamping force evenly, minimizing surface damage, while the external hex drive facilitates efficient installation with standard tools. Perfect for HVAC, automotive, and electronics enclosures, these screws ensure durable, maintenance-free fastening in demanding industrial applications.

Specification Summary & Compliance
