Value Collection R63034681 Machine Screw 4-40 Oval Slotted

Product Description

The VALUE COLLECTION R63034681 is a 4-40 UNC machine screw designed for precision fastening in light-duty mechanical and electrical assemblies. This screw features an oval head profile with a slotted drive, allowing installation with a standard flat-blade screwdriver. The body is machined from 18-8 stainless steel, providing solid corrosion resistance in environments where moisture or mild chemicals are present. At 0.375 inches in overall length, this fastener is sized for thin panel, chassis, and component mounting applications common in electrical enclosures, instrumentation, and control panels.

This screw is suited for residential and commercial applications where a low-profile, countersunk oval head is required on metal or plastic substrates. HVAC technicians, electricians, and mechanical assemblers use fasteners of this type when securing covers, terminal strips, and sub-assemblies in control boxes and equipment panels. The 4-40 thread is a standard UNC designation common across instrumentation and light mechanical hardware. The bright, uncoated finish maintains dimensional consistency for use in threaded inserts and tapped holes. This item is sold in a minimum order quantity of 100 pieces per order.

Key Features

• 4-40 UNC thread for compatibility with standard tapped holes and threaded inserts in light mechanical assemblies
• Oval head profile provides a low countersunk appearance flush-to-slightly-raised above the mounting surface
• Slotted drive accepts standard flat-blade screwdrivers — no specialty tooling required
• 18-8 stainless steel construction resists corrosion in damp or mildly corrosive service environments
• Bright uncoated finish maintains precise thread tolerances and dimensional accuracy
• Overall length of 0.375 inches suits thin panel and chassis fastening tasks

Compatibility

Designed as a standard 4-40 UNC machine screw for use in any application requiring an oval-head slotted fastener in that thread size and length.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver sized to the slotted head. De-energize any electrical equipment before fastening or removing screws in control panels or enclosures, following applicable NEC guidelines. Ensure the receiving hole is properly tapped to 4-40 UNC before installation to avoid cross-threading or fastener damage. Do not over-torque into plastic or thin-sheet substrates.
