S-91185A901 10-32 x 3/8" Thumb Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term durability in humid or demanding industrial environments.
• Black Acetal plastic head provides excellent electrical insulation and a comfortable, non-slip grip for hand-tightening without tools.
• Precision Class 3A thread fit guarantees secure, vibration-resistant fastening with minimal risk of cross-threading in high-accuracy assemblies.
• Fine thread spacing (UNF) delivers superior holding power and finer adjustment control compared to coarse threads.
• Two-arm thumb screw design allows for quick installation and removal, reducing assembly time in maintenance and prototyping applications.
• Wide operating temperature range (32° to 180°F) maintains performance stability in varied climatic or indoor conditions.
• Full threading along the 3/8" length enables deep engagement and consistent clamping force across the entire fastener.

Professional Applications & Engineering Value

These 10-32 UNF thumb screws combine the strength of 18-8 stainless steel with the lightweight, insulating properties of a black Acetal plastic head, making them ideal for applications requiring frequent adjustments and reliable electrical isolation. The Class 3A thread fit and fine thread spacing ensure precise, secure fastening in electronic enclosures, instrumentation panels, and machinery where vibration resistance is critical. Their right-hand thread direction and two-arm design facilitate rapid manual operation, reducing tool dependency in assembly lines or field service. Engineered to withstand temperatures from 32° to 180°F, these screws provide consistent performance in industrial controls, telecom equipment, and laboratory devices, solving common issues of corrosion, slippage, and installation inefficiency.
