Professional Applications & Engineering Value
These zinc-plated steel Torx pan head screws deliver critical advantages for industrial assembly applications where vibration resistance and corrosion protection are paramount. The 8-32 UNC coarse thread configuration provides excellent pull-out resistance in metals and plastics, while the T20 Torx drive system eliminates the stripping issues common with Phillips heads in high-torque applications. The fully threaded design ensures maximum grip length for secure fastening in variable material thicknesses. Engineered with Rockwell B70 hardness, these rounded head screws maintain structural integrity in machinery, electrical enclosures, and automotive components where repeated stress cycles would compromise inferior fasteners.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent mating with nuts and tapped holes. Complies with ASME B18.6.3 mechanical specifications for pan head machine screws. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. Features right-hand threaded configuration with 0.164" thread diameter and 3/8" length for standardized industrial applications.
