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

Product Description

The VALUE COLLECTION 1-CDR-10-M7- is a winged iron thumb screw designed for tool-free fastening in assemblies that require frequent hand-tightening and loosening. Built to UNC thread standards with a 1/4-20 thread size, this screw features a 2-inch length under the head and an overall length of 2-5/8 inches. The uncoated iron construction suits general-purpose indoor mechanical and industrial applications. The winged head design provides a positive grip surface, allowing technicians to apply adequate torque without a driver. Material grade 32510 iron delivers adequate strength for light-duty clamping and positioning tasks.

This thumb screw is suited for use in light mechanical assemblies, fixtures, jigs, and equipment panels where hand-operated fastening is needed. The with-shoulder configuration aids in alignment and load distribution against mating surfaces. The 7/16-inch shoulder diameter and 1-3/8-inch head diameter make it compatible with standard panel thicknesses commonly found in shop equipment, enclosures, and fabricated fixtures. Typical installers include machinists, technicians, and maintenance personnel working on mechanical assemblies requiring regular access.

Key Features

• Winged head for tool-free hand tightening and loosening
• 1/4-20 UNC thread for compatibility with standard tapped holes
• With-shoulder design aids alignment and surface load distribution

Compatibility

Designed as a general-purpose replacement or stock thumb screw for assemblies using 1/4-20 UNC tapped holes in light mechanical, fixture, and equipment panel applications.

Installation Notes

Installation is performed by hand without tools due to the winged head design. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading. Do not over-torque by hand; winged thumb screws are intended for light clamping loads only. Verify thread engagement is adequate for the application before putting the assembly into service.
