Electro Hardware THS3009M07F16 Thumb Screw 6-32 Knurled 303 Ss

Product Description

The ELECTRO HARDWARE THS3009M07F16 is a 303 stainless steel thumb screw with a knurled head, designed for tool-free fastening in applications where frequent hand-tightening and loosening are required. The 6-32 UNC thread pattern and 5/8-inch overall length make it a compact, reliable fastener for light-duty panel, enclosure, and instrumentation work. The knurled head provides grip without requiring a driver, and the uncoated 303 stainless finish offers good corrosion resistance in mildly corrosive or washdown environments. This screw is sold individually and is intended for use by electricians, HVAC technicians, and panel fabricators who need a hand-operable fastener that meets QQ-S-763 material standards.

This thumb screw is well suited for residential and commercial electrical enclosures, control panels, instrumentation housings, and light mechanical assemblies where repeated access is needed. The without-shoulder design keeps the profile low and the thread engagement straightforward. Typical installations include access panels, junction boxes, and equipment covers where tools may not be available or practical. The 7/16-inch thread length provides adequate engagement depth for standard panel thicknesses used in these applications.

Key Features

• 303 stainless steel construction meets QQ-S-763 material standard for corrosion resistance
• 6-32 UNC thread for compatibility with standard tapped holes in enclosures and panels
• Knurled head allows tool-free hand tightening and removal
• Without-shoulder design suits flush or low-profile panel fastening
• Uncoated finish eliminates coating flake contamination risk in sensitive assemblies
• Compact 5/8-inch overall length fits tight clearance installations

Compatibility

Designed as an OEM-style replacement or service fastener for applications requiring a 6-32 UNC knurled thumb screw in 303 stainless steel with a without-shoulder configuration.

Installation Notes

Installation does not require tools under normal hand-tightening conditions, but a flat-blade screwdriver may be used if additional torque is needed. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which can occur with stainless fasteners. Power down or de-energize any enclosure or panel before removing or installing fasteners on live equipment. Follow applicable NEC guidelines when fastening electrical enclosure covers.
