Professional Applications & Engineering Value

This high-profile knurled thumb screw delivers exceptional engineering value where frequent adjustments and tool-free operation are critical. The 18-8 stainless steel construction provides reliable corrosion resistance in industrial environments, while the 1/2"-13 UNC coarse thread enables rapid installation and removal cycles. The fully threaded design ensures consistent engagement across the entire 1-1/2" length, making it ideal for machinery access panels, electronic enclosures, and production jigs requiring repeated access. The knurled head texture combined with the high-profile round shape offers superior tactile grip even with gloves, solving slippage issues common in high-vibration applications.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit standards with UNC coarse threading (1/2"-13) and right-hand thread direction. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulation adherence for global industrial applications. Thread specifications maintain ISO-compatible tolerances for reliable interchangeability in inch-based fastening systems.
