Value Collection 583855PR 3/8-16 Round Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 583855PR is a 3/8-16 slotted round head machine screw designed for general-purpose mechanical fastening in metal assemblies. Manufactured from alloy steel with a zinc finish for basic corrosion resistance, this screw measures 1-3/4 inches in length under the head and features Unified National Coarse (UNC) threading. The round head profile sits above the mating surface and is driven with a standard flat-blade screwdriver. This fastener is a practical, workhorse choice for maintenance techs, millwrights, and fabricators who need reliable threaded fastening without specialized tooling.

Suited for use in light industrial, mechanical, and general trade applications where UNC thread engagement into tapped holes or with mating nuts is required. The zinc coating provides a modest barrier against oxidation in dry to mildly humid environments. This screw is appropriate for interior mechanical assemblies, equipment panels, junction box covers, and similar applications where an exposed round head profile is acceptable. Minimum order quantity is 100 pieces per order.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and hex nuts
• 1-3/4 inch length under head for moderate fastening depth
• Round head profile with slotted drive accepts standard flat-blade screwdrivers
• Alloy steel construction for solid mechanical strength
• Zinc finish provides basic corrosion resistance in dry environments
• No washer — bare underhead seating for flush clamping against the mating surface

Compatibility

Designed as a standard UNC machine screw for use in any application requiring a 3/8-16 threaded fastener with a round slotted head profile in alloy steel.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted head. Always ensure the mating tapped hole or nut matches the 3/8-16 UNC thread specification before driving. De-energize and lock out any equipment before accessing fastener locations on powered assemblies. Do not exceed the mechanical torque rating appropriate for alloy steel fasteners of this diameter — consult applicable engineering or code references for torque specifications.
