S-90841A240 10-32 x 1" ASME B18.3 High-Vacuum Cleaned-and-Bagged Vented Socket Head Screws

Key Features & Benefits at a Glance

• Superior vacuum integrity with specialized venting (0.052" diameter) prevents gas entrapment and ensures reliable performance in high-vacuum environments
• Exceptional corrosion resistance from 18-8 stainless steel construction maintains integrity in harsh industrial conditions and cleanroom applications
• Precision thread engagement with Class 3A fit provides secure fastening with minimal play and consistent torque transmission
• High mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness withstands heavy loads and repeated assembly cycles
• Optimized drive performance through standard hex socket design (5/32" drive) prevents cam-out and enables high-torque applications
• Regulatory compliance assurance meets ASME B18.3 specifications and environmental standards (RoHS 3, REACH) for global industrial acceptance
• Fine thread advantage with 10-32 UNF configuration offers superior vibration resistance and precise adjustment capabilities

Professional Applications & Engineering Value

Engineered for high-vacuum systems and precision equipment, these socket head cap screws solve critical challenges in semiconductor manufacturing, aerospace components, and scientific instrumentation. The vented design actively prevents virtual leaks by allowing trapped gases to escape during pump-down cycles, while the 18-8 stainless steel construction maintains dimensional stability in ultra-clean environments. The Class 3A thread fit ensures precise engagement in threaded inserts and mounting plates, reducing the risk of cross-threading in delicate assemblies. With UNF fine threads providing enhanced clamping force distribution, these fasteners deliver reliable performance in applications where vibration resistance and repeatable disassembly are paramount requirements.

Specification Summary & Compliance

This 10-32 UNF threaded socket head cap screw maintains Class 3A thread fit tolerances per ASME B18.3 specifications, ensuring precision engagement in demanding applications. The fastener features a standard hex drive socket (5/32") and right-hand thread orientation with full threading along the 1" length. Manufacturing compliance includes adherence to ASME B18.3 dimensional standards, RoHS 3 (2015/863/EU) restrictions on hazardous substances, and REACH (EC 1907/2006) chemical regulations for industrial use in regulated markets.
