Electro Hardware MTHS3008M07F16 Thumb Screw M3.5x0.6

Product Description

The ELECTRO HARDWARE MTHS3008M07F16 is a 303 stainless steel thumb screw with a knurled head, designed for hand-tightened fastening applications where tools are not required or practical. The M3.5 x 0.6 metric thread runs the full length at 16 mm overall. The knurled head measures 8 mm in diameter and 5 mm in height, providing a firm grip surface for repeated manual adjustment. The 303 stainless steel construction resists corrosion in light to moderate exposure environments and is left uncoated from the factory. This fastener is installed by technicians and assemblers working on enclosures, panels, and equipment requiring frequent access.

This thumb screw is suited for use in HVAC control panels, electrical enclosures, plumbing access covers, and light industrial equipment assemblies where hand-tool-free fastening is needed. Its metric M3.5 x 0.6 thread standard makes it appropriate for metric-spec equipment and component mounting. The uncoated 303 stainless finish is compatible with applications requiring moderate corrosion resistance without additional surface treatment. Install environments include indoor mechanical rooms, equipment panels, and service access points on residential and light commercial systems.

Compatibility

Designed as a standard metric M3.5 x 0.6 thumb screw suitable for equipment panels, enclosures, and assemblies specifying a knurled-head stainless fastener in this thread size.

Installation Notes

This thumb screw is installed by hand and requires no special tooling under normal conditions. De-energize or power down any electrical panel or control enclosure before removing or replacing fasteners on access covers. Inspect mating threads for damage or contamination before installation to avoid galling, which stainless steel fasteners are more susceptible to than carbon steel. Apply a small amount of anti-seize compound to the threads if the fastener will be removed frequently or exposed to moisture.
