Electro Hardware THS1099M07F16 Thumb Screw 10-32

Product Description

The ELECTRO HARDWARE THS1099M07F16 is a 303 stainless steel thumb screw with a knurled head and shoulder, designed for tool-free fastening in trade and industrial applications. The 10-32 UNC thread runs with a 0.9375-inch overall length, a 7/16-inch (0.4375-inch) head diameter, and a 3/16-inch head height. The shoulder measures 3/8-inch in diameter and 1/8-inch in length. The uncoated 303 stainless steel body offers solid corrosion resistance for use in enclosures, panels, and equipment where frequent manual adjustment is required.

This thumb screw is suited for electrical enclosure panels, HVAC equipment covers, control cabinets, and light mechanical assemblies where a fastener needs to be tightened or removed by hand without tools. The knurled head provides a secure grip in field conditions. The shoulder design helps locate and retain mating components during assembly, making it a practical choice for service technicians who perform repeated access to equipment panels.

Installation Notes

Installation is performed by hand without tools; ensure the mating tapped hole is clean and free of debris before threading. De-energize any electrical enclosure or panel before accessing internal components or replacing fasteners. Avoid cross-threading by aligning the screw straight before engaging. Consult NEC guidelines when working inside electrical enclosures.
