Value Collection R63066444 3/8-16 X 2 in Flat Head Slotted Screw

Product Description

The VALUE COLLECTION R63066444 is a 3/8-16 x 2 inch flat head machine screw designed for general fastening applications in metal, wood, and composite assemblies. It features a slotted drive and a flat countersunk head profile that sits flush with or below the surface of the mating material when properly installed. Machined from 18-8 stainless steel with a bright, uncoated finish, it offers solid corrosion resistance in wet, outdoor, or chemically exposed environments. Thread specification follows the Unified National Coarse (UNC) standard. Overall length is 2 inches, with 2 inches measured under the head.

This screw is suited for mechanical assemblies, structural fastening, and maintenance applications where a flush-mount fastener and corrosion resistance are required. Typical users include machinists, millwrights, plumbers, HVAC technicians, and general maintenance professionals working on equipment panels, brackets, enclosures, and structural supports. The 3/8-16 UNC thread engages standard tapped holes and threaded inserts across a wide range of commercial and industrial equipment.

Key Features

• 3/8-16 UNC thread for compatibility with standard tapped holes and threaded hardware
• Flat countersunk head sits flush with the mating surface for clean, low-profile installations
• Slotted drive accepts standard flat-blade screwdrivers and slot-drive bits
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Bright uncoated finish — no plating to chip, flake, or introduce dimensional inconsistency
• 2-inch overall length with full 2-inch length under head for deep engagement applications

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes across general mechanical, structural, and equipment-maintenance applications.

Installation Notes

Install using a flat-blade screwdriver or slotted bit sized to the screw head. Ensure the mating hole is countersunk to the correct angle to allow the flat head to seat fully flush. Apply appropriate thread engagement depth per fastener sizing standards — the UNC thread requires a properly tapped or pre-threaded hole. Avoid overtightening stainless steel fasteners in stainless steel tapped holes, as galling can occur; use an anti-seize compound where needed.
