Value Collection SBRI-1004000-100BX Machine Screw 10-24

Product Description

The VALUE COLLECTION SBRI-1004000-100BX is a 10-24 x 4-inch round head slotted machine screw made from Grade 2 steel with a zinc-plated finish. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty applications. The slotted drive accepts a standard flat-blade screwdriver, making it a straightforward choice for general fastening work. Length is measured under the head at 4 inches, and the thread pattern follows the Unified National Coarse (UNC) standard. This screw ships in a box quantity of 100. It is used by electricians, HVAC technicians, plumbers, millwrights, and general maintenance professionals across a wide range of trade and industrial applications.

These machine screws are suited for light to medium fastening tasks in residential, commercial, and light industrial settings. Common applications include panel assembly, equipment mounting, junction box hardware, and general mechanical assembly where a UNC 10-24 thread form is specified. The round head profile sits above the surface and distributes load over a wider bearing area compared to flat head styles. No washer is included or required by design.

Key Features

• 10-24 UNC thread form for broad compatibility with standard tapped holes and nuts
• 4-inch length under head for deeper engagement in thicker assemblies
• Round head style provides a wider bearing surface without countersinking
• Slotted drive works with standard flat-blade screwdrivers and bits
• Zinc-plated Grade 2 steel finish for basic corrosion resistance in dry or light-duty environments
• Sold in a box of 100 for job-site and shop use

Compatibility

Designed for use in any application requiring a 10-24 UNC threaded fastener with a round slotted head. Compatible with standard 10-24 tapped holes, threaded inserts, and hex nuts conforming to UNC standards.

Installation Notes

Install using a flat-blade screwdriver or slotted bit sized to the screw head to avoid cam-out and head damage. De-energize any electrical equipment before fastening hardware inside panels or enclosures, following NFPA 70 (NEC) lockout/tagout requirements. Do not overtorque Grade 2 fasteners, as they have lower tensile strength than Grade 5 or Grade 8 hardware. Inspect threads on mating components before installation to ensure clean engagement and prevent cross-threading.
