Value Collection 43057 5/16-24 Unf Steel Flush Press Fit Insert 25pk

Product Description

The VALUE COLLECTION 43057 is a flush press fit threaded insert designed to create strong, permanent internal threads in metal assemblies. Made from steel, this insert is driven into a pre-drilled hole and sits flush with the surrounding surface, providing a clean, low-profile threaded receptacle. The 5/16-24 UNF thread standard makes it compatible with fine-thread fastening applications common in precision assemblies. Each insert measures 0.615 inches in overall length with an insert diameter of 0.528 inches. Sold in a pack of 25 units, this insert is used by machinists, millwrights, and maintenance professionals working on light industrial and mechanical assemblies.

This insert is suited for applications where a flush surface finish is required after installation. The press fit design allows installation into pre-drilled holes sized to 17/32 inches, providing a reliable thread anchor in base materials including sheet metal frames, brackets, and fabricated steel components. Typical uses include equipment repair, fixture fabrication, and OEM assembly work where UNF threaded connections are specified.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press or hand drill to prepare the hole to the specified 17/32 inch diameter before pressing the insert in place. A proper press fit tool or arbor press is recommended to seat the insert without distortion. Ensure the workpiece is secured and the mating surface is clean and free of burrs prior to installation. Do not attempt to drive the insert with impact tools, as this may damage the thread form or cause the insert to seat at an angle.
