Value Collection R50000277 Flat Head Machine Screw 3/8-16

Product Description

The VALUE COLLECTION R50000277 is a 3/8-16 x 1-1/2 inch flat head slotted machine screw designed for general fastening applications across mechanical, structural, and fabrication work. Made from Grade 2 steel with a zinc-plated finish, this screw provides reliable corrosion resistance in standard indoor and light-duty outdoor environments. The flat head profile sits flush with or below the surface of the mated material, making it well suited for applications where a low-profile or recessed finish is required. The slotted drive accommodates a standard flat-blade screwdriver or bit. Thread spec is 3/8-16 UNC coarse thread with an overall length of 1-1/2 inches.

This machine screw is commonly used in light industrial assembly, equipment maintenance, and general fabrication where UNC coarse-thread fasteners are specified. The zinc plating provides a baseline level of corrosion protection appropriate for indoor mechanical assemblies, panel mounting, and similar applications. Machinists, maintenance technicians, and general contractors working with steel or threaded inserts will find this screw a standard-stock item. Sold in a minimum order quantity of 50 pieces per order.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and threaded hardware
• Flat head profile sits flush with the workpiece surface for a clean, low-profile finish
• Slotted drive works with standard flat-blade screwdrivers and bits
• Grade 2 steel construction provides adequate tensile strength for general-duty fastening
• Zinc-plated finish offers baseline corrosion resistance for indoor and light-duty applications
• Overall length of 1-1/2 inches with no washer; length under head equals overall length

Compatibility

Designed as a standard UNC coarse-thread machine screw compatible with 3/8-16 tapped holes, threaded inserts, and hex nuts conforming to inch-series fastener standards.

Installation Notes

Install using a flat-blade screwdriver or slotted bit sized to fit the drive recess without slipping. Ensure the mating tapped hole or nut is clean and free of debris before threading. Do not overtighten, as Grade 2 fasteners have lower proof load ratings than Grade 5 or Grade 8 hardware. For structural or load-bearing applications, verify that Grade 2 meets the specified fastener grade requirements before installation.
