Electro Hardware THS1053M07F16 Thumb Screw 8-32 Knurled

Product Description

The ELECTRO HARDWARE THS1053M07F16 is a 303 stainless steel thumb screw with a knurled head and integral shoulder, designed for hand-tightened fastening applications in panel assembly, enclosure work, and light mechanical assemblies. The 8-32 UNC thread is a widely used coarse-thread standard in trade and industrial environments. The knurled head provides secure finger grip without requiring tools. Overall length is 5/8 inches, with a 7/16-inch head diameter and a 3/16-inch head height. The shoulder measures 3/8 inch in diameter and 1/8 inch in length, providing a precise locating surface. The uncoated 303 stainless steel construction resists corrosion in moderately demanding environments.

This thumb screw is suited for use in HVAC control panel assembly, electrical enclosure access hardware, instrumentation mounting, and similar applications where frequent hand removal and reinstallation is required. The 8-32 thread size makes it compatible with standard tapped holes and threaded inserts common in sheet metal and light structural components. Electricians, HVAC technicians, and mechanical assemblers working with control enclosures and equipment panels will find this fastener appropriate for panel retention and access cover applications.

Key Features

• 303 stainless steel body with uncoated finish for corrosion resistance in moderate-duty environments
• Knurled head design allows hand tightening and removal without tools
• Integral shoulder at 3/8 inch diameter by 1/8 inch length for accurate component positioning
• 8-32 UNC thread standard for broad compatibility with common tapped hardware
• 5/8-inch overall length suits standard panel and enclosure wall thicknesses
• Meets multiple material and finish standards including ASTM B633 and QQ-S-763

Compatibility

Designed as a standard 8-32 UNC thumb screw for use in tapped holes or threaded inserts in sheet metal panels, enclosures, and light mechanical assemblies requiring tool-free fastening.

Installation Notes

Install by hand into a pre-tapped or insert-threaded 8-32 hole. Ensure mating threads are clean and free of debris before installation. Do not use power tools to drive this thumb screw, as the knurled head is not rated for tool torque and thread or head damage may result. This fastener is intended for hand-tight applications only.
