Professional Applications & Engineering Value
Engineered for B2B industrial applications requiring frequent access or adjustments, this nylon thumb screw solves critical assembly challenges. The knurled round head with raised profile delivers exceptional hand-tightening capability where tool access is limited, while the 1/4"-20 UNC coarse thread ensures rapid installation in plastics, electronics, and machinery panels. Its nylon plastic construction provides electrical insulation and resistance to chemicals, making it ideal for electrical enclosures, laboratory equipment, and packaging machinery. The temperature resistance from -40° to 185°F maintains dimensional stability in varying operational environments, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This thumb screw maintains Class 2A thread fit tolerance for consistent engagement with standard UNC threaded components. Manufactured to Unified National Coarse (UNC) 1/4"-20 threading specifications with full threading along the 1" length. Complies with RoHS 3 (2015/863/EU) regulations restricting hazardous substances, ensuring environmental responsibility in industrial supply chains. The dimensional accuracy includes 35/64" head diameter with 27/64" collar diameter for optimal load distribution during hand-tightening applications.
