Professional Applications & Engineering Value

These No. 8 x 3/4" 410 stainless steel DST thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming design eliminates the risk of chip accumulation that can compromise joint integrity in electronic enclosures, automotive components, and consumer products. The blunt tip configuration and 18 TPI thread pitch work synergistically to displace plastic material without creating stress concentrations that lead to cracking. The Phillips drive system provides reliable torque transmission while the pan head design offers a low-profile finish suitable for various industrial applications. Manufactured from 410 stainless steel, these fasteners maintain their mechanical properties in environments where moisture or chemical exposure would degrade alternative materials.

Specification Summary & Compliance

These precision-engineered thread forming screws feature a 0.164" thread diameter with 18 threads per inch and 3/4" length in right-hand threading configuration. The pan head design measures 0.27" in diameter with 0.097" height, compatible with Phillips No. 2 drive tools. Manufactured to exacting standards for plastic fastening applications, these screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest requirements for restricted substances and chemical safety in industrial applications.
