Value Collection 45204 Knurled Body Threaded Insert 1/4-20

Product Description

The VALUE COLLECTION 45204 is a knurled body open end threaded insert designed for permanent installation into pre-drilled holes in metal assemblies. The knurled exterior bites into the parent material during press-in installation, creating a secure, torque-resistant hold. This insert accepts 1/4-20 UNC fasteners and is manufactured from 1008/1010 steel with a clear protective zinc yellow dichromate finish for corrosion resistance. Overall length is 0.58 inches with an insert diameter of 0.39 inches. Mechanical and maintenance technicians use these inserts to add or restore threaded holes in sheet metal, enclosures, and structural panels.

This threaded insert is suited for light-gauge sheet metal and panel fabrication applications common in HVAC equipment assembly, electrical enclosures, and similar trade installations. The open end design allows through-bolt engagement, and the 1/4-20 UNC thread standard ensures broad fastener compatibility. Minimum grip is 0.027 inches and maximum grip is 0.165 inches, making it appropriate for thin to moderate material thicknesses. Sold in a pack of 50 units.
