Electro Hardware EFH-832-5 Captive Stud 8-32 Steel

Product Description

The ELECTRO HARDWARE EFH-832-5 is a zinc-plated steel captive stud designed for secure, panel-mounted fastening in sheet metal assemblies and light industrial enclosures. With an 8-32 thread size and an overall length of 0.3125 inches (5/16 inches), this stud is engineered to retain a threaded connection point permanently within a panel. The minimum panel thickness requirement is 0.04 inches, making it suitable for thin-gauge sheet metal applications. Manufactured from C1005 to C1018 low-carbon steel with a zinc finish, it delivers adequate corrosion resistance for indoor and light-duty enclosure environments. Electricians, OEM assembly technicians, and panel fabricators typically install this type of fastener during initial enclosure build or retrofit work.

Captive studs like the EFH-832-5 are used in electrical enclosures, control panels, HVAC equipment housings, and light industrial sheet metal assemblies where a fixed threaded stud must remain attached to the panel even when the mating nut is removed. The 0.04-inch minimum panel thickness specification suits 22-gauge and thicker steel sheet stock commonly found in commercial and residential equipment cabinets. Package quantity is 50 units per package, with a minimum order quantity of 1.

Key Features

• 8-32 unified coarse thread for standard compatibility with UNC fastener hardware
• Overall length of 5/16 inches (0.3125 inches) for compact, low-profile panel installations
• Minimum panel thickness of 0.04 inches accommodates thin-gauge sheet metal
• Zinc-plated C1005 to C1018 low-carbon steel construction for strength and corrosion resistance in indoor environments
• Head height of 0.09 inches keeps the installed profile close to the panel surface
• Sold in packages of 50 units, suitable for production runs and service inventory

Compatibility

Designed as an OEM-style captive stud replacement or new-installation fastener for thin-gauge steel panels requiring an 8-32 threaded anchor point in electrical enclosures and equipment housings.

Installation Notes

Captive studs are typically installed by electricians or mechanical assembly technicians during panel fabrication or enclosure modification. Always de-energize and lockout any electrical enclosure before installing or replacing panel fasteners. Installation typically requires appropriate press or insertion tooling to seat the stud without damaging the panel or the stud threads. Verify that the panel material thickness meets the 0.04-inch minimum requirement before installation to ensure proper retention.
