Au-ve-co Products 24174 Hex Head Cap Screw 1/4-20

Product Description

The AU-VE-CO PRODUCTS 24174 is a 1/4-20 hex head cap screw machined from steel with a black oxide finish. It measures 1.1875 inches under the head and drives with a 7/16-inch hex wrench or socket. The black oxide coating provides a modest layer of corrosion resistance while reducing light reflection, making this fastener a standard choice in mechanical assemblies, HVAC equipment brackets, electrical enclosures, and general trade applications. Installation requires no specialty tooling beyond a standard hex drive. Technicians and tradespeople reach for this size frequently when securing light-gauge brackets, panels, and component mounts across residential and commercial systems.

This screw is suited for use in threaded steel assemblies calling for a 1/4-20 inch thread pitch. Typical applications include securing HVAC unit panels, motor mounts, electrical enclosure covers, and other structural or equipment-mounting tasks where a black oxide steel fastener is specified. It ships in a minimum order quantity of 50 pieces, making it practical for service vans, shop stock, and small-run installations where consistent fastener availability matters. The unified inch thread form is compatible with standard 1/4-20 tapped holes and hex nuts found across common trade equipment.

Key Features

• 1/4-20 unified inch thread for compatibility with standard tapped holes and hardware
• 1.1875-inch length under head provides adequate thread engagement in typical bracket and panel applications
• Steel construction delivers reliable tensile strength for general mechanical fastening
• Black oxide finish offers light corrosion resistance and low-glare appearance
• 7/16-inch hex drive accepts standard wrenches and sockets
• Sold in minimum quantities of 50 to support stocking and repetitive installation work

Compatibility

Designed as a standard inch-series hex head cap screw for use in any assembly, equipment mount, or panel application requiring a 1/4-20 threaded fastener in steel with a black oxide finish.

Installation Notes

Installation is performed by hand-starting the screw into a properly tapped or pre-threaded 1/4-20 hole, then driving to snug with a 7/16-inch wrench or socket. De-energize and lock out all electrical or mechanical equipment before removing or replacing fasteners on live systems. Avoid cross-threading by confirming thread engagement is smooth before applying torque. Follow applicable equipment manufacturer guidelines and relevant mechanical or electrical codes for fastener specifications in your application.
