Value Collection R63060929 Flat Head Machine Screw 3/8-16

Product Description

The VALUE COLLECTION R63060929 is a 3/8-16 UNC flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. It measures 1-1/4 inches in overall length and 1-1/4 inches under the head, making it a fully threaded fastener in this configuration. The flat head profile sits flush with or below the mating surface when properly countersunk, which is critical in assemblies where a protruding head would interfere with clearance or mating parts. The slotted drive accepts a standard flat-blade screwdriver. Licensed tradespeople and maintenance technicians working in corrosion-prone environments rely on 18-8 stainless for its resistance to rust and oxidation without the cost of higher-alloy grades.

This screw is suited for light to medium fastening applications in HVAC equipment panels, plumbing fixtures, electrical enclosures, and general industrial or maintenance assembly. The 3/8-16 UNC coarse thread provides reliable engagement in tapped holes in steel, aluminum, or plastic components. Grade 18-8 stainless makes it appropriate for both indoor and outdoor installations where moisture exposure is a factor. This item is sold in a minimum order quantity of 5 pieces.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Flat head profile countersinks flush with mating surface to eliminate protrusion
• Slotted drive accepts standard flat-blade screwdrivers — no specialty tooling required
• 18-8 stainless steel construction resists corrosion and oxidation in wet or outdoor environments
• Bright uncoated finish — no plating to flake, chip, or contaminate the assembly
• 1-1/4 inches overall length with full thread length under head

Compatibility

Designed as a standard 3/8-16 UNC flat head slotted machine screw for use in any application requiring a countersunk fastener with a coarse unified thread in that size.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or tradesperson familiar with fastener torque requirements for the specific mating material and application. Always verify the receiving hole is properly countersunk to the correct angle for a flat head screw before driving. Avoid over-torquing stainless fasteners, as galling can occur — apply an anti-galling compound when threading into stainless tapped holes. De-energize and lock out any equipment before accessing fasteners on live panels or enclosures.
