Professional Applications & Engineering Value
This 6-32 UNC thumb screw combines the corrosion-resistant properties of 18-8 stainless steel with the ergonomic advantages of a knurled black acetal plastic head to address common assembly challenges. The low-profile round head design minimizes protrusion while the coarse thread enables rapid installation in equipment panels, electronic enclosures, and machinery access points. Engineers benefit from the Class 3A thread fit precision that prevents loosening under vibration, making these industrial thumb screws ideal for maintenance-heavy applications where repeated access is required. The right-hand thread direction provides intuitive operation, while the dual thumb and hex drive options accommodate both quick adjustments and torque-critical installations.
Specification Summary & Compliance
Manufactured to precise UNC thread standards with Class 3A fit tolerance for superior thread engagement. The 6-32 thread size features coarse spacing with 0.138" diameter and full threading along the 21/32" length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. The acetal plastic head maintains integrity across its specified temperature range while the stainless steel body provides consistent mechanical performance.
