• Full threading along the 1-1/4" length provides consistent grip and superior pull-out strength across the entire fastened joint.

Professional Applications & Engineering Value

These No. 10-12 thread forming screws are precision-engineered to solve common fastening challenges in sheet metal assembly. The 18-8 Stainless Steel composition offers excellent resistance to oxidation and corrosion, making these oval head Phillips screws suitable for HVAC systems, electronic enclosures, and automotive panels exposed to moisture. The A/AB tapping screw type and pointed tip allow for easy starting and form strong, load-bearing threads that resist vibration loosening. The 82° countersink angle of the oval head ensures a secure, flush fit, eliminating snag points and providing a clean finish for both structural and aesthetic applications. This combination of material and design delivers long-term reliability, reducing maintenance needs and total cost of ownership.
