Value Collection R63066442 Machine Screw 3/8-16 X 2.5 in

Product Description

The VALUE COLLECTION R63066442 is a flat head slotted machine screw designed for general fastening applications requiring a flush or countersunk finish. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance in wet or chemically exposed environments. The 3/8-16 UNC thread pattern provides strong clamping force, and the overall length of 2.5 inches accommodates moderate material stack-ups. Installers in HVAC, plumbing, electrical, and mechanical trades reach for 18-8 stainless fasteners where mild steel would corrode or where code requires non-ferrous hardware.

This screw suits residential and light commercial installations where a flush-mounted fastener is needed. The flat head profile seats flush with or below the material surface when driven into a properly countersunk hole. The slotted drive accepts a standard flathead screwdriver, making it accessible in the field without specialized bits. Length is measured overall, and no washer is included with this fastener. Minimum order quantity is 5 pieces.

Key Features

• 3/8-16 UNC thread for strong, unified-coarse thread engagement
• 2.5-inch overall length suits moderate-depth countersunk assemblies
• 18-8 stainless steel construction resists corrosion in damp or exposed environments
• Flat head profile allows flush or below-surface seating in countersunk holes
• Slotted drive compatible with standard flathead screwdrivers
• Bright, uncoated finish — no plating to chip or flake in service

Compatibility

Designed as a standard 3/8-16 UNC flat head slotted machine screw suitable for use in metal, plastic, or composite assemblies that require a countersunk fastener with inch-standard threading.

Installation Notes

A properly sized countersink must be prepared in the mating material before installation to allow the flat head to seat flush. Use a calibrated torque driver or wrench to avoid overdriving, which can damage the slotted drive recess or strip the thread. Shut down and de-energize any equipment before replacing or installing fasteners in electrical or mechanical enclosures. Consult applicable codes such as NEC or IFGC for fastener material requirements in specific trade applications.
