Professional Applications & Engineering Value
This M3 thumb screw delivers critical engineering advantages where frequent access and tool-free operation are required. The 18-8 stainless steel material provides excellent corrosion resistance for electrical enclosures, instrumentation panels, and outdoor equipment. The knurled head texture ensures positive grip even with oily gloves, while the flared collar design prevents pull-through in plastic and sheet metal applications. With Class 6g thread fit and coarse pitch threading, these metric thumb screws offer rapid installation in production environments and maintain secure fastening in vibrating machinery. The combination of 80,000 PSI tensile strength and full threading makes them ideal for critical access panels, medical devices, and aerospace components requiring reliable yet removable fastening solutions.
Specification Summary & Compliance
This thumb screw features M3 x 0.5 mm coarse thread with Class 6g thread fit per metric standards, 6mm length with full threading, and Rockwell B85 hardness. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for regulated industries including electronics, medical equipment, and consumer products.
