- Standardized quality manufactured to ASTM A581/A582 specifications for consistent mechanical performance
Professional Applications & Engineering Value
This 6-32 UNC thumb screw delivers exceptional value in panel assembly applications where frequent access and reliable fastening are critical. The 18-8 stainless steel construction provides excellent resistance to corrosion and oxidation, making it suitable for electronics enclosures, industrial control panels, and medical equipment subjected to repeated maintenance cycles. The knurled head offers superior tactile grip even with gloved hands, while the partially threaded design prevents cross-threading and ensures proper panel alignment. With right-hand thread direction and slotted drive compatibility, installers benefit from multiple operation methods in space-constrained environments where tool access may be limited.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with UNC coarse threading (6-32 size) ensuring reliable engagement in panel applications. Complies with ASTM A581/A582 material specifications for consistent mechanical properties and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for restricted substance compliance. The inch system measurements maintain precision across all dimensional characteristics including head diameter (0.313") and thread length (7/32").
