Value Collection 31138 Machine Screw 10-24 1-1/4 in Round Slotted 50pk

Product Description

The VALUE COLLECTION 31138 is a 10-24 UNC machine screw designed for general-purpose fastening in mechanical assemblies, HVAC equipment, electrical enclosures, and light industrial applications. It features a round head profile with a slotted drive and is manufactured from alloy steel with a zinc-plated finish for corrosion resistance in standard indoor environments. The screw measures 1-1/4 inches in length under the head, conforming to the inch system of measurement. Sold in a pack of 50, this fastener is suited for technicians and tradespeople who need a reliable, off-the-shelf screw in quantity for service work or panel assembly.

This screw is used wherever a 10-24 UNC thread pattern and round slotted head are required. Common applications include securing control panels, mounting brackets, equipment housings, and junction box covers in HVAC, electrical, and light mechanical installations. The zinc plating provides a baseline level of corrosion protection appropriate for indoor or sheltered installations. The slotted drive is compatible with standard flat-blade screwdrivers, making it practical for field service work with basic toolsets.

Key Features

• 10-24 UNC thread for compatibility with standard inch-system tapped holes
• Round head profile provides a low-profile, finished appearance on panel surfaces
• Slotted drive works with common flat-blade screwdrivers
• Alloy steel construction for strength in mechanical fastening applications
• Zinc-plated finish offers corrosion resistance in dry indoor environments
• Pack of 50 units suited for service stock and bulk installation tasks

Compatibility

Designed as a standard inch-system fastener for use in any application requiring a 10-24 UNC thread, round head, slotted-drive machine screw without a washer face.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to fit a standard slotted machine screw head. Ensure the mating tapped hole or nut matches the 10-24 UNC thread specification before driving. De-energize electrical equipment and follow applicable NEC or equipment manufacturer lockout-tagout procedures before fastening or removing screws in live panels or enclosures. Do not overtighten, as alloy steel screws in thin sheet metal or plastic-threaded holes can strip the mating thread.
