Value Collection 1-CDJ-10-M7- Iron Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION 1-CDJ-10-M7- is a winged iron thumb screw sized for 1/4-20 UNC thread applications. It features a 3/4-inch length under the head, a 1-3/8-inch head diameter, and a 5/8-inch head height, making it easy to tighten and loosen by hand without tools. The shoulder design adds stability and alignment when seated in a mating clearance hole. The uncoated iron construction suits general-purpose fastening in light mechanical assemblies, enclosures, panels, and jigs. Maintenance technicians, fabricators, and field service pros use this style of thumb screw wherever tool-free adjustment or quick-release access is required.

This thumb screw is suited for residential and light commercial applications including electrical enclosures, equipment panels, HVAC access covers, and workshop fixtures. The winged head allows repeated hand-tightening and removal without tooling, which is useful in service scenarios where panels are accessed frequently. The 7/16-inch shoulder diameter helps locate the fastener consistently in matching bored or drilled holes.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes

Compatibility

Designed as a general-purpose replacement or service thumb screw for standard 1/4-20 UNC tapped applications in panels, enclosures, and light mechanical assemblies.

Installation Notes

De-energize and lock out any electrical enclosure or equipment before servicing fasteners on live panels. Thread engagement should be confirmed by hand before final seating to avoid cross-threading. Iron thumb screws are not rated for high-torque or structural load applications — use only in light clamping and access-panel retention service. Follow applicable NEC or equipment manufacturer guidelines when used on electrical enclosures.
