Key Features & Benefits at a Glance
- Superior holding power with a 0.414" flange diameter that distributes load evenly and prevents pull-through in sheet metal.
- Efficient thread forming design creates strong, permanent threads in pre-drilled holes without generating chips, ideal for ductile materials.
- High-torque external hex drive combined with a slotted head allows for versatile installation with common hand or power tools.
- Fully threaded pointed tip ensures easy starting and maximum thread engagement along the entire 3/8" length for a secure fit.
- Optimized for No. 21 drill bits, simplifying the assembly process for materials up to 0.025" thick.
- Compliant with RoHS 3 and REACH regulations, guaranteeing they are safe for use in regulated industrial environments.
- Durable construction with a No. 10-12 thread profile providing reliable fastening strength in demanding sheet metal applications.
Professional Applications & Engineering Value
This No. 10 thread forming tapping screw is engineered to solve common fastening challenges in sheet metal assembly. Its Type A thread forming design displaces material to create a zero-clearance fit, which provides exceptional resistance to vibration loosening and enhances joint integrity. The hex flanged head eliminates the need for a separate washer, speeding up installation and providing a larger bearing surface to protect soft materials from damage. The fully threaded body and pointed tip ensure quick alignment and deep engagement, making it a reliable industrial screw for HVAC systems, electronic enclosures, and automotive panels where durability and regulatory compliance are critical.
Specification Summary & Compliance
This screw conforms to standard inch dimensions with a No. 10-12 thread (0.19" diameter, 12 TPI) and a 3/8" length. It is designed as a thread forming screw for use with a No. 21 drill bit (0.159" diameter) in materials with a maximum thickness of 0.025". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances for industrial safety.
