Professional Applications & Engineering Value
Engineered for industrial applications requiring frequent adjustments and secure fastening, this 18-8 stainless steel thumb screw delivers exceptional value through its knurled head texture that prevents slippage during manual operation. The UNC coarse threading and Class 2A thread fit ensure reliable engagement in metal, plastic, and composite materials, while the low-profile round head design minimizes protrusion in confined spaces. With 80,000 psi tensile strength and corrosion-resistant properties, this partially threaded thumb screw maintains integrity in manufacturing equipment, electronic enclosures, and machinery requiring repeated access. The combination of slotted drive compatibility and environmental compliance makes it ideal for maintenance-heavy environments where tool accessibility and regulatory adherence are critical.
Specification Summary & Compliance
This thumb screw features precision 1/2"-13 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy. Manufacturing adheres to inch system standards with partial threading extending 1-15/16" on a 2" overall length. The component is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
