Electro Hardware THS3043M07F16 Thumb Screw 10-32 303 Ss

Product Description

The ELECTRO HARDWARE THS3043M07F16 is a 303 stainless steel thumb screw with a knurled head, designed for tool-free fastening in light-duty mechanical and electronic assemblies. The 10-32 UNC thread and 5/8-inch overall length make it well suited for panel access covers, enclosure doors, and instrument housings where repeated removal is required. The knurled head provides positive grip without requiring a driver. At a head diameter of 7/16 inches and head height of 3/16 inches, the low-profile head keeps clearance requirements minimal. The uncoated 303 stainless construction offers corrosion resistance in moderate environments. Licensed tradespeople and OEM assembly technicians are the primary installers.

This thumb screw is used in light commercial and industrial applications including electrical enclosures, HVAC control panels, instrumentation racks, and equipment access covers. The 10-32 UNC thread engages standard tapped holes and inserts found in sheet metal panels and machined components across electrical, mechanical, and plumbing equipment assemblies. It is sold individually per package, with a minimum order of 2 pieces.

Installation Notes

Install by hand into a pre-tapped or threaded insert hole. Power down or de-energize any enclosure before removing or replacing access panel fasteners. Do not overtighten — stainless steel fasteners are susceptible to galling when driven with excessive force. No special tools are required for hand installation.
