Value Collection MSRI03705500-050BX Machine Screw 3/8-16

Product Description

The VALUE COLLECTION MSRI03705500-050BX is a 3/8-16 x 5.5-inch round head slotted machine screw manufactured from alloy steel with a zinc-plated finish. It meets ASME B18.6.3 dimensional standards, ensuring consistent thread engagement and head geometry across production batches. The 3/8-16 unified coarse thread provides strong clamping force in steel and other ferrous assemblies. The slotted drive accepts a standard flat-blade screwdriver or bit. These fasteners are sold in a minimum order quantity of 50 pieces, making them suited for production, maintenance, and repair applications where consistent fastener stock is required.

This screw is used in general mechanical assembly, structural fabrication, and equipment maintenance wherever a 3/8-16 coarse-thread fastener with a low-profile round head is specified. The round head style provides a larger bearing surface than flat or pan heads in clearance holes, and the zinc plating offers moderate corrosion resistance in indoor or dry environments. Typical installers include millwrights, maintenance mechanics, fabricators, and field service technicians working on industrial or commercial equipment.

Key Features

• 3/8-16 unified coarse thread for high pull-out strength in steel assemblies
• 5.5-inch length measured under the head per ASME B18.6.3
• Round head profile with slotted drive for flat-blade tool compatibility
• Alloy steel construction for higher tensile strength than low-carbon alternatives
• Zinc-plated finish provides moderate corrosion resistance in dry environments
• Sold in boxes of 50 to support production and maintenance stocking

Compatibility

Designed as a standard 3/8-16 coarse-thread machine screw conforming to ASME B18.6.3, compatible with any tapped hole or nut meeting 3/8-16 UNC thread specifications in inch-system assemblies.

Installation Notes

Installation is performed by mechanics, fabricators, or maintenance technicians using a flat-blade screwdriver or slotted bit of appropriate tip width to prevent cam-out. Ensure the mating tapped hole or nut is clean and free of debris before driving. Apply thread lubricant or anti-seize as required by the assembly specification. De-energize and lock out any equipment before replacing fasteners on live machinery.
