Value Collection R63094281 Machine Screw 3/8-16 X 1-1/4 in

Product Description

The VALUE COLLECTION R63094281 is a 3/8-16 UNC round head slotted machine screw machined from brass and finished bright with no coating. Measuring 1-1/4 inches in length under the head, this fastener is designed for general mechanical assembly work where a corrosion-resistant, non-magnetic metal fastener is required. The slotted drive accepts a standard flat-blade screwdriver, making it a straightforward choice for maintenance, repair, and original equipment assembly tasks. Electricians, plumbers, HVAC technicians, and industrial maintenance pros reach for brass screws when working near dissimilar metals or in environments where steel hardware would corrode.

This screw is suited to residential and light commercial applications where a 3/8-16 unified coarse thread pattern is called for. Common use cases include panel assembly, terminal block mounting, equipment enclosures, and plumbing fixture hardware where brass compatibility matters. The round head profile sits above the work surface and is appropriate where a low-profile or flush finish is not required. No washer is included or integrated into the design.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped holes
• 1-1/4 inch length measured under the head
• Round head profile for above-surface seating without a countersunk bore
• Slotted drive accepts standard flat-blade screwdrivers
• Solid brass construction, bright uncoated finish, non-magnetic and corrosion-resistant
• No washer — clean installation where washer-style hardware is not needed

Compatibility

Designed for use in any application requiring a 3/8-16 UNC round head slotted machine screw in brass. Fits standard inch-series tapped holes and hex nuts conforming to the 3/8-16 unified coarse thread specification.

Installation Notes

Install with a flat-blade screwdriver sized to the slot to avoid cam-out and slot damage. Apply appropriate thread engagement — a minimum of one full diameter of thread engagement is standard practice for steel or brass tapped holes. Do not overtorque brass fasteners, as the material is softer than steel and threads can strip at lower torque values. Power down or de-energize any equipment before accessing fastener locations inside electrical enclosures.
