Electro Hardware THS1012M07F16 Thumb Screw 6-32 Ss

Product Description

The ELECTRO HARDWARE THS1012M07F16 is a 303 stainless steel thumb screw with a knurled head and shoulder, designed for hand-tightened fastening applications where tools are not practical or convenient. The 6-32 UNC thread and 3/4 inch overall length make it well suited for panel assemblies, enclosures, and access covers in HVAC, electrical, and mechanical equipment. The knurled head measures 3/8 inch in diameter and 3/16 inch in height, providing adequate grip surface for finger-tightening in tight spaces. The 303 stainless steel body delivers corrosion resistance in humid or wet service environments, and the uncoated finish is compatible with standard hardware assemblies.

This thumb screw is used in light industrial, commercial, and residential service applications where frequent panel removal or adjustment is required without tools. The shoulder design — 0.312 inch shoulder diameter with a 1/8 inch shoulder length — provides positive seating and prevents over-insertion into mating hardware. It is commonly installed by HVAC technicians, electricians, and equipment service professionals during panel and cover assembly or field servicing of control enclosures and electrical boxes.

Key Features

• 303 stainless steel construction for corrosion resistance in humid environments
• 6-32 UNC thread compatible with standard imperial hardware
• Knurled head for secure finger-tightening without tools
• Shoulder design (0.312 inch diameter, 1/8 inch length) for positive seating
• Uncoated finish — no risk of coating interference with mating surfaces
• Brass head material provides dimensional stability and grip texture

Compatibility

Designed as a standard 6-32 UNC thumb screw for use in panel assemblies, control enclosures, and equipment covers requiring hand-tightened fasteners. Meets ASTM B633, QQ-S-763, QQ-N-290A, QQ-S-633, and related standards.

Installation Notes

Install and remove by hand only — do not use power tools or wrenches on the knurled head, as this can strip threads or damage the head profile. De-energize and lock out all electrical equipment before accessing any panel or enclosure secured by these screws. Verify that the mating threaded insert or nut is rated for 6-32 UNC engagement before installation. Follow applicable NEC or equipment manufacturer guidelines for fastener specifications on electrical enclosures.
