Professional Applications & Engineering Value

This 18-8 stainless steel TRS tapping screw delivers exceptional engineering value for plastic assembly applications where material integrity and long-term performance are critical. The thread forming design with Tri-Lobe shank cross-section creates strong, permanent threads in plastic substrates without requiring pre-tapped holes, eliminating the risk of chip formation that can compromise electronic components or sensitive assemblies. The combination of 0.164" thread diameter and 16 TPI thread pitch provides optimal stress distribution in plastic materials, preventing material cracking while ensuring superior pull-out strength. The Phillips flat head configuration with standard profile allows for flush mounting in countersunk holes, creating clean finished appearances in consumer products, electronic enclosures, and industrial plastic components.

Specification Summary & Compliance

This No. 8 x 1-1/4" TRS tapping screw features inch system measurements with fully threaded right-hand direction and blunt tip design. The screw maintains precise dimensional accuracy with 0.164" thread diameter, 16 TPI thread density, and standardized 82° countersink angle for proper seating. Manufacturing compliance includes adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications without hazardous substance restrictions.
