Value Collection 31154 Machine Screw 12-24 1.5in Round Head 50pk

Product Description

The VALUE COLLECTION 31154 is a 12-24 UNC machine screw with a round head and slotted drive, manufactured from alloy steel with a zinc-plated finish. It measures 1.5 inches in length, measured under the head, and is supplied without a washer. The zinc plating provides basic corrosion resistance for general-purpose indoor and light-duty mechanical assembly applications. These fasteners are sized for use with a standard flat-blade screwdriver and are threaded to the Unified National Coarse standard. Each package contains 50 screws, making them suitable for moderate-volume maintenance, repair, or production tasks. Licensed tradespeople and maintenance technicians working on equipment panels, junction boxes, brackets, and similar assemblies will find this a standard utility fastener.

The 31154 slotted round head machine screw is intended for general mechanical and electrical assembly work where a low-profile round head and simple slotted drive are specified. Typical applications include panel mounting, light structural brackets, electrical enclosure assembly, and equipment maintenance across residential and light commercial settings. The 12-24 thread size is a common coarse-thread designation found in a wide range of standard tapped holes and threaded inserts used in HVAC, electrical, and plumbing equipment enclosures.

Key Features

• 12-24 UNC thread for compatibility with standard coarse-thread tapped holes and inserts
• 1.5-inch length measured under the head for accurate fastener selection
• Round head profile provides a low-profile, finished appearance on visible panel surfaces
• Slotted drive for use with standard flat-blade screwdrivers
• Alloy steel construction for solid mechanical strength in general-duty applications
• Zinc-plated finish for basic corrosion resistance in indoor environments

Compatibility

Designed as a general-purpose machine screw for use in any application specifying a 12-24 UNC round head slotted fastener with a 1.5-inch under-head length.

Installation Notes

Installation requires a flat-blade screwdriver sized to fit the slotted head. Ensure the receiving hole or threaded insert matches the 12-24 UNC thread specification before driving the fastener. Do not overtighten, as over-torquing can strip the alloy steel threads or damage the mating material. Follow applicable equipment manufacturer guidelines and relevant codes such as NFPA 70 when installing fasteners in electrical enclosures.
