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

Product Description

The VALUE COLLECTION 1-CDL-10-17- is a zinc-plated iron thumb screw with a winged head, designed for hand-tightening applications that require frequent adjustment or removal without tools. The 1/4-20 UNC thread and 1 inch length under head make it suitable for light-duty clamping, panel fastening, and fixture assembly across HVAC, electrical, and general mechanical trades. The winged head provides a secure grip surface, while the zinc plating offers basic corrosion resistance for indoor and sheltered installations. The shoulder design adds stability and helps maintain alignment during installation.

This thumb screw is intended for applications where tool-free fastening is preferred, such as securing access panels, jigs, fixtures, and equipment covers. It fits standard 1/4-20 UNC tapped holes and is sized for light mechanical assemblies in residential and light commercial settings. The 1-3/8 inch head diameter and 5/8 inch head height provide adequate surface area for hand operation. Installers in HVAC, electrical, and general maintenance trades will find this fastener appropriate for panel and cover attachment points that require regular service access.
