Value Collection 1-CDT-10-17- Iron Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION 1-CDT-10-17- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not practical or available. Built to a 1/4-20 UNC thread standard, this thumb screw features a 3-inch length under the head and a zinc finish that provides basic corrosion resistance. The winged head allows for secure finger-grip torque without the need for a driver or wrench. With a head diameter of 1-3/8 inches and a head height of 5/8 inches, it delivers a stable clamping surface in light-duty mechanical assemblies, fixtures, and enclosures.

This thumb screw suits applications in industrial maintenance, machine guarding, electrical enclosures, HVAC access panels, and general equipment assembly where frequent removal and reinstallation is required. The shoulder design adds alignment and load-bearing capability at the joint interface. It is appropriate for use by maintenance technicians, millwrights, and field service professionals working with iron-compatible fastener applications in inch-measurement systems.

Compatibility

Designed as a standard 1/4-20 UNC inch-series thumb screw for use in any application requiring a winged, hand-operated fastener with a shoulder in that thread size.

Installation Notes

Installation requires a matching 1/4-20 UNC tapped hole or nut. Verify thread engagement depth before applying load. Power down or de-energize any equipment before accessing panels or enclosures secured by this fastener. Do not exceed hand-tight torque for iron fasteners of this grade to avoid thread stripping.
