Value Collection R63066248 Machine Screw 1/2-13 X 1-1/2 in

Product Description

The VALUE COLLECTION R63066248 is a flat head, slotted machine screw designed for general-purpose fastening in mechanical assemblies, fixtures, and structural connections. Manufactured from 18-8 stainless steel with a bright, uncoated finish, it delivers reliable corrosion resistance in both indoor and light outdoor applications. The screw measures 1/2-13 thread size with an overall length of 1-1/2 inches and follows Unified National Coarse (UNC) thread standards. The flat head profile allows the fastener to sit flush with or countersink into the mating surface, making it well suited for assemblies where a low-profile installation is required. Licensed trades and industrial maintenance technicians are the primary installers.

This machine screw is appropriate for use in residential and light commercial mechanical, HVAC, plumbing, and electrical panel assemblies where a corrosion-resistant, flush-mount fastener is needed. The 1/2-13 UNC thread is a widely used coarse-thread standard, making this screw compatible with a broad range of tapped holes, threaded inserts, and standard nuts found throughout trade and industrial work. It is sold individually per package with a minimum order quantity of 2 units.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and humid environments
• Flat head profile enables flush or countersunk installation in mating surfaces
• Slotted drive accepts standard flat-blade screwdrivers and bits

Compatibility

Designed as a standard UNC machine screw for use with any tapped hole, hex nut, or threaded insert sized to 1/2-13 specifications in inch-measurement systems.

Installation Notes

Install using a flat-blade screwdriver or slotted bit of appropriate size to avoid cam-out or fastener damage. Ensure the mating hole is correctly tapped to 1/2-13 UNC before installation. De-energize and lock out any equipment before accessing fastened panels or enclosures. When used in structural or pressure-retaining applications, consult applicable mechanical codes for required fastener specifications and torque guidance.
