• Full thread depth (1") enabling maximum engagement strength for heavy-duty applications

Professional Applications & Engineering Value

This 1"-14 fine thread cap nut delivers exceptional performance in demanding industrial settings where vibration resistance and environmental protection are critical. The zinc-plated steel construction provides sacrificial corrosion protection, significantly outperforming uncoated fasteners in humid or chemically aggressive environments. The Class 2B thread fit ensures consistent engagement with mating components while accommodating minor misalignments common in high-volume assembly operations. With its external hex drive and standard profile, this cap nut offers superior torque transmission for secure installations in machinery, structural frameworks, and heavy equipment where fine threads provide enhanced clamping force and precision adjustment capabilities. The combination of UNS thread standards and inch measurement system guarantees compatibility with North American industrial equipment specifications.

Specification Summary & Compliance

This precision cap nut features 1"-14 fine thread spacing with Class 2B thread fit per UNS standards, ensuring dimensional accuracy and reliable performance. Manufactured from zinc-plated steel with dimensions of 1 7/16" width and 1 35/64" height, it provides consistent mechanical properties across production batches. The product maintains full compliance with RoHS 3 (2015/863/EU) regulations under exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental standards for industrial components.
