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

Product Description

The VALUE COLLECTION 1-DEN-10-17- is a winged iron thumb screw intended for applications requiring hand-tightening without tools. The fastener features a 5/16-18 UNC thread, a 1-1/4 inch length under the head, and an overall length of 2 inches. The winged head design provides grip surface for finger tightening, making it suited for access panels, jigs, fixtures, and adjustment assemblies in mechanical and HVAC installations. A zinc finish provides basic corrosion resistance. The shoulder type is with shoulder, and the shoulder diameter measures 9/16 inch. This screw is sold individually and is produced to material grade 32510 iron.

This thumb screw is appropriate for light-duty mechanical assemblies, equipment covers, and field-adjustable components in residential and light commercial trade applications. The winged head style is commonly used where frequent removal and reinstallation is required without a screwdriver or wrench, such as filter access doors, service panels, and bracket adjustments in HVAC, plumbing, and electrical enclosures.

Installation Notes

This fastener is installed by hand in applications where a tool-free connection is required. Always verify the mating thread specification matches 5/16-18 UNC before installation. De-energize or shut down any equipment before servicing access panels or fastener assemblies. Do not over-torque by hand; winged thumb screws are designed for finger-tight clamping force only.
