Professional Applications & Engineering Value

This 18-8 stainless steel thumb screw with spade head design solves critical industrial fastening challenges where tool-free operation and corrosion resistance are paramount. The 3/8"-16 UNC coarse thread provides rapid installation in equipment panels, access doors, and machinery guards, while the fully threaded right-hand configuration ensures maximum holding power in vibration-prone environments. Engineers specify this thumb screw for maintenance-intensive applications because the generous head surface area enables secure hand-tightening even with gloves. The stainless steel construction maintains integrity in manufacturing facilities, outdoor equipment, and marine applications where moisture and chemicals would degrade inferior fasteners.

Specification Summary & Compliance

This thumb screw features 3/8"-16 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy and reliable mating with standard components. The 3/4" length and 0.375" thread diameter provide optimal fastening capability for medium-duty applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring restriction of hazardous substances for workplace safety and regulatory compliance.
