Value Collection 1-DES-10-17- Iron Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION 1-DES-10-17- is a winged iron thumb screw designed for hand-tightening applications where tools are impractical or unnecessary. Built to a 5/16-18 UNC thread standard, it measures 2-1/2 inches in length under the head and 3-1/4 inches in overall length. The winged head provides a positive grip surface for finger-driven installation and removal. A zinc finish offers basic corrosion resistance. This fastener is suited for panels, covers, and access doors in mechanical, HVAC, electrical, and general trade assemblies where frequent removal is required.

This thumb screw is a standard inch-measurement fastener used across residential and commercial trade applications. Typical install scenarios include securing access panels on air handlers, electrical enclosures, and equipment covers where repeated hand access is needed. The shoulder design locates the fastener precisely in the mating hole, reducing wobble and wear over repeated cycles. It is sold individually and is appropriate for use by HVAC technicians, electricians, and plumbers maintaining equipment with serviceable covers.

Key Features

Compatibility

Designed as a standard 5/16-18 UNC inch-series thumb screw suitable for tapped holes in equipment panels, access covers, and mechanical enclosures requiring hand-removable fasteners.

Installation Notes

Hand-thread into a 5/16-18 tapped or nut-equipped hole. Power down or de-energize any equipment before removing or installing access panel fasteners. Do not use a wrench or driver on the winged head, as the head is designed for hand torque only and may be damaged by tool force. Verify thread engagement is sufficient before applying load to the assembly.
