S-96562A831 10-32 x 3/4" ASME B18.6.3 Thread-Locking Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent nylon patch ensures reliable fastening in high-stress environments, eliminating the need for separate locking hardware
• Superior corrosion resistance from 18-8 stainless steel construction and passivated finish extends service life in humid or chemically aggressive conditions
• High-strength performance with 60,000 psi tensile strength and Rockwell B70 hardness withstands heavy mechanical loads without deformation
• Wide temperature compatibility maintains locking integrity across extreme conditions from -70°F to 250°F
• Precision thread engagement with Class 2A UNF fine threads provides smooth installation and secure fit in tapped holes
• Optimized drive efficiency through Phillips No. 2 drive design enables quick installation while resisting cam-out during torque application
• Full thread coverage along the 3/4" length ensures maximum grip strength and uniform stress distribution

Professional Applications & Engineering Value

These nylon patch locking screws solve critical vibration-induced loosening problems in industrial assemblies where maintaining clamp load is essential. The 18-8 stainless steel construction with passivated finish provides exceptional resistance to oxidation and chemical exposure, making these pan head screws ideal for electronic enclosures, machinery guards, and outdoor equipment subjected to environmental stressors. The UNF fine threading offers superior engagement in thinner materials and precision components, while the permanent nylon patch locking technology eliminates maintenance cycles by creating a consistent friction fit that outperforms mechanical lock washers. These fully threaded fasteners deliver reliable performance in automotive subsystems, industrial control panels, and marine applications where thermal cycling and vibration are constant challenges.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance ensuring precise dimensional accuracy. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features standard UNF 10-32 fine threads with right-hand direction and fully threaded 3/4" length. The nylon patch locking system maintains performance across the specified temperature range of -70°F to 250°F while the passivated finish enhances corrosion protection on the underlying 18-8 stainless steel material.
