Product Description

The VALUE COLLECTION 1-DES-07-17- is a winged iron thumb screw sized at 5/16-18 UNC thread with a 2-1/2 inch length under the head and an overall length of 3-1/4 inches. The winged head design allows hand-tightening without tools, making it a practical fastener for applications requiring frequent removal or adjustment. Finished in zinc for basic corrosion resistance, the screw features a shoulder construction and is manufactured to material grade 32510 iron. It weighs 0.1 pounds. This fastener is suited for use in assemblies where hand-operated clamping or securing is needed across HVAC, plumbing, electrical panel, or general mechanical service work.

This thumb screw is appropriate for residential and light commercial trade applications where a finger-turn fastener is required. The 5/16-18 UNC thread is a common size found in equipment access panels, cover plates, jigs, fixtures, and service assemblies. The shoulder design helps locate and align mating components during installation. Technicians in HVAC, electrical, and general mechanical trades will find this screw a reliable hand-tighten fastener for service access points and field-fabricated assemblies.
