Value Collection A98158 Flat Head Machine Screw 50-pack

Product Description

The VALUE COLLECTION A98158 is a 10-24 UNC flat head machine screw with a pin-in-Torx drive, manufactured from 18-8 stainless steel with a bright, uncoated finish. Each screw measures 1/2 inch in overall length. The flat head profile sits flush with the mating surface when fully seated, making it a common choice in panel assembly, electrical enclosures, and light structural fastening. The 18-8 stainless steel construction provides solid corrosion resistance in general indoor and moderate outdoor service conditions. The pin-in-Torx drive requires a matching security bit, which helps deter unauthorized removal in restricted-access installations. These screws are sold in a pack of 50.

This screw is suited for trade and industrial applications where a flush-mount fastener is required in stainless steel. Typical uses include mounting covers on electrical panels, securing access panels in HVAC equipment, attaching fixtures in plumbing utility spaces, and general mechanical assembly work. The 10-24 thread is a widely used coarse-thread size in inch-measurement fastener applications, and the 1/2-inch overall length fits standard sheet metal and light-gauge material assemblies. The pin-in-Torx drive makes this fastener appropriate for installations where tamper resistance is a requirement.

Compatibility

Designed for use in any application requiring a 10-24 UNC threaded flat head machine screw with a 1/2-inch overall length in 18-8 stainless steel.

Installation Notes

A pin-in-Torx security bit of the correct size is required for installation and removal — standard Torx bits will not engage properly. Always ensure the receiving hole is tapped to 10-24 UNC before driving. De-energize electrical equipment and follow applicable NEC guidelines before fastening or servicing panels or enclosures. Do not overtighten into thin sheet metal; use the appropriate torque for the base material per applicable industry standards.
