Value Collection 580438PR 10-32 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 580438PR is a 10-32 x 1-1/4 inch overall length flat head machine screw designed for general fastening applications across mechanical, electrical, and light structural assemblies. It features a slotted drive and a flat head profile that sits flush with the mating surface when properly countersunk. Constructed from Grade 2 steel with a zinc finish, this screw provides basic corrosion resistance suitable for indoor and light-duty environments. It uses Unified National Fine (UNF) thread form, which provides tighter thread engagement and greater resistance to vibration loosening compared to coarse thread variants. Technicians and assemblers working on panels, brackets, enclosures, and equipment housings will find this screw a standard fit for many common 10-32 tapped hole applications.

This screw is widely used in HVAC control panel assembly, electrical enclosure fabrication, light mechanical assemblies, and general equipment maintenance. The flat head style requires a countersunk or flat-bottomed clearance hole to seat flush. The 10-32 UNF thread size is a common standard in low-voltage control boards, fan motor brackets, and sheet metal panel work. It is typically installed by HVAC technicians, electricians, and mechanical assemblers as a replacement or bulk stock fastener in service and production environments.

Key Features

• 10-32 UNF thread for tight, vibration-resistant engagement in fine-threaded tapped holes
• Flat head profile seats flush when used with a properly countersunk hole
• Slotted drive compatible with standard flathead screwdrivers and bits
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc finish provides basic corrosion resistance for indoor and light-duty use
• 1-1/4 inch overall length suits moderate panel thickness and bracket applications

Compatibility

Designed as a general-purpose replacement and stock fastener for any assembly or equipment requiring a 10-32 UNF flat head slotted machine screw with a 1-1/4 inch overall length.

Installation Notes

Install using a flathead screwdriver or slotted bit driver sized for the screw head. Ensure the receiving hole is tapped to 10-32 UNF specification and countersunk appropriately for a flush flat head seating. Power down any electrical equipment before fastening screws into or near live panels or control boards. Avoid over-torquing, as Grade 2 steel has lower tensile strength than higher-grade fasteners.
