Value Collection -94653-1 4-40 X 5/8 in Pan Head Screw 50pk

Product Description

The VALUE COLLECTION -94653-1 is a 4-40 x 5/8-inch pan head Phillips machine screw made from 18-8 stainless steel with a bright, uncoated finish. Designed to the unified national coarse (UNC) thread standard, this screw is suited for light-duty fastening tasks in electrical enclosures, control panels, HVAC equipment covers, and general mechanical assemblies. The 18-8 stainless steel construction provides corrosion resistance in mildly harsh environments. This package contains 50 pieces, making it a practical bench stock item for service technicians and installers who need reliable, standardized hardware on hand for field repairs and equipment assembly.

This fastener is used across residential and commercial trade applications wherever a 4-40 UNC thread pattern is required. Common installation scenarios include securing control board mounting hardware, terminal block assemblies, panel covers, and light-gauge sheet metal components. The pan head profile distributes clamping load over a wider bearing surface compared to flat-head designs, making it well-suited for thin material fastening. No washer is included or required under the head. Thread engagement is measured from directly under the head, with a length under head of 5/8 inches.

Key Features

• 4-40 UNC thread size for compatibility with standard 4-40 tapped holes and nuts
• 5/8-inch length under head for consistent thread engagement in light-gauge assemblies
• 18-8 stainless steel construction resists corrosion in moderately wet or humid environments
• Pan head profile provides a wider bearing surface without requiring a washer
• Phillips drive type compatible with standard No. 1 Phillips screwdrivers and bits
• Bright, uncoated finish suitable for applications where surface treatment is not required

Compatibility

Designed as a standard 4-40 UNC machine screw suitable for use in any application requiring a 4-40 tapped hole or 4-40 hex nut, including electrical panels, control boards, and light mechanical enclosures.

Installation Notes

Install using a No. 1 Phillips screwdriver or a matching bit driver set to low torque to avoid stripping the stainless steel threads. De-energize any electrical panel or control board before installing or removing fasteners in live equipment. Do not mix stainless steel fasteners with dissimilar metals in highly conductive or galvanically active environments without appropriate isolation. Follow applicable NEC or equipment manufacturer guidelines when fastening components inside electrical enclosures.
