Value Collection A98159 Flat Head Machine Screw 10-24

Product Description

The VALUE COLLECTION A98159 is a flat head machine screw designed for general-purpose fastening applications across a wide range of industries. It features a 10-24 UNC thread size and measures 3/4 inches in overall length. The screw is manufactured from 18-8 stainless steel, which provides solid corrosion resistance in both indoor and outdoor environments. The drive type is Pin In Torx, a tamper-resistant configuration that requires a matching Torx bit with center pin for installation or removal. The bright, uncoated finish reflects the natural appearance of the stainless steel base material. This screw ships in a package quantity of 50 pieces.

This flat head machine screw is suited for use in light fabrication, panel assembly, enclosure mounting, and maintenance applications where a flush or countersunk surface is required. The 10-24 UNC thread is a standard coarse-thread size widely used in metal-to-metal fastening in HVAC, electrical, plumbing, and general mechanical work. The Pin In Torx drive makes this screw appropriate for applications requiring tamper resistance, such as access panels, equipment enclosures, and secure mounting points in commercial and light industrial settings. Installers in multiple trades will encounter this thread size as a standard throughout the field.

Compatibility

Designed as a standard 10-24 UNC flat head machine screw for use in any pre-tapped or clearance-drilled application requiring that thread size and a countersunk flat head profile.

Installation Notes

Installation requires a Pin In Torx driver bit sized to match the screw head. Always ensure the mating hole is properly tapped to 10-24 UNC or that a suitable nut is used on the back side. Power down or de-energize any equipment before driving screws into or around electrical enclosures, control panels, or live assemblies. Do not over-torque stainless steel fasteners into tapped aluminum or softer materials, as galling can occur.
