Electro Hardware ECLS-0524-2 Clinch Nut 5/16-24 Ss 5pk

Product Description

The ELECTRO HARDWARE ECLS-0524-2 is a round-head clinch captive nut designed for permanent installation into sheet metal panels. This fastener presses into a drilled or punched hole and, once clinched, becomes a fixed, non-rotating threaded insert that accepts a 5/16-24 UNF screw. Constructed from 18-8 stainless steel with a passivated finish, it resists corrosion in demanding service environments. The head diameter measures 0.5 inches, the mounting hole diameter is 0.413 inches, and the head height is 0.23 inches. Minimum panel thickness for proper clinching is 0.0909 inches. This part ships in a package of 5.

Clinch captive nuts are used in HVAC enclosures, electrical panels, control cabinets, and light structural assemblies where a threaded anchor must be installed from one side of the panel. They are common in original equipment manufacturing and field repair scenarios where welded or riveted inserts are not practical. The 5/16-24 thread size suits medium-load fastening applications across both commercial and residential equipment. Licensed sheet metal workers, electricians, and HVAC technicians install these as part of panel fabrication or equipment service.

Compatibility

Designed as an OEM-style clinch captive nut for sheet metal panels meeting a minimum thickness of 0.0909 inches with a 0.413 inch mounting hole diameter and a 5/16-24 UNF thread requirement.

Installation Notes

Installation requires a press or squeeze-action tool that applies even force to seat the clinch nut flush against the panel surface. Power down any equipment and remove panel sections before installing or replacing clinch hardware. Ensure the mounting hole diameter matches the 0.413 inch specification before pressing to avoid improper seating. Do not attempt to install by striking with a hammer, as this can distort the head or damage the panel.
