Professional Applications & Engineering Value

These 10-32 UNF rounded head slotted screws deliver exceptional engineering value in precision assemblies where fine thread spacing and reliable performance are critical. The 18-8 stainless steel construction combined with passivated finish provides superior corrosion resistance, solving common failure points in moisture-prone industrial environments. The high, narrow fillister head profile offers improved tool clearance while maintaining a low-profile appearance, making them ideal for electronic enclosures, precision instruments, and machinery where space optimization matters. With fully threaded design and Class 2A thread fit, these screws ensure consistent clamping force and vibration resistance in applications requiring repeated maintenance or adjustment.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNF thread form (10-32 size). Complies with ASME B18.6.3 specifications for mechanical properties and dimensional requirements. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions. Features include: 1/4" length, 0.19" thread diameter, fine thread spacing, and full threading throughout the shank length.
