Electro Hardware MTHS3044M07L21m Thumb Screw M6x1

Product Description

The ELECTRO HARDWARE MTHS3044M07L21m is a 303 stainless steel thumb screw with a knurled head, designed for hand-tightening applications where tools are not required or practical. The M6 x 1 metric thread allows secure fastening into standard M6 threaded holes or nuts. The knurled head provides a positive grip surface for repeated finger-tightened installations and removals. With a head diameter of 13 mm and a head height of 6 mm, this fastener suits panels, enclosures, and equipment covers that require frequent access. The uncoated 303 stainless steel construction resists corrosion in moderate environments while maintaining dimensional stability.

This thumb screw is suited for light industrial, HVAC enclosure, electrical panel, and equipment assembly applications where tool-free fastening is preferred. It is commonly installed on removable access covers, junction box lids, and control panel doors in both commercial and residential settings. The metric M6 x 1 thread standard makes it compatible with metric-threaded assemblies across a wide range of trade and industrial equipment. It ships individually and is available for single-unit purchase.

Installation Notes

This fastener is installed by hand into a pre-threaded M6 x 1 hole or mating nut. Electricians, HVAC technicians, and mechanical assemblers commonly use this style of fastener on enclosures and access covers. De-energize all electrical equipment before servicing any panel or enclosure that uses these fasteners. Do not use power tools to drive knurled thumb screws, as over-torquing can strip threads or damage the knurled head.
