Value Collection 92919 4-40 X 0.5 in Pan Head Slotted Screw 50pk

Product Description

The VALUE COLLECTION 92919 is a 4-40 x 0.5 inch pan head machine screw designed for precision fastening in light mechanical assemblies. Manufactured from 18-8 stainless steel with a bright, uncoated finish, it offers solid corrosion resistance in both indoor and mildly corrosive environments. The slotted drive accepts a standard flat-blade screwdriver. Length is measured under the head. These screws ship in a 50-piece package, making them practical for service technicians who need a reliable supply on hand for panel covers, brackets, and small component mounting.

This screw is suited for residential and commercial applications where a small-diameter, fine-thread fastener is required. Common install scenarios include securing electrical enclosure panels, mounting low-voltage control boards, attaching nameplates, and fastening light sheet metal components. The 4-40 UNC thread form is a widely used standard in control panel and electronic equipment assembly, making this screw a practical bench and field stock item for HVAC, electrical, and plumbing service technicians.

Key Features

• 4-40 UNC thread for use in standard tapped holes found in control panels and small equipment enclosures
• 0.5 inch length under head suits thin panel and bracket fastening
• 18-8 stainless steel construction provides corrosion resistance without plating
• Pan head profile distributes clamping load over a wider bearing surface
• Slotted drive compatible with standard flat-blade screwdrivers
• Bright uncoated finish — no risk of coating flaking into sensitive assemblies

Compatibility

Designed as a standard 4-40 UNC machine screw suitable for any tapped hole or nut conforming to 4-40 Unified National Coarse thread specifications in inch-measurement fastener applications.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver. Always power down and de-energize electrical equipment before accessing enclosures or control panels. Avoid over-torquing small-diameter screws in tapped plastic or thin sheet metal to prevent thread damage. Verify thread engagement depth before final tightening to ensure full pull-out resistance.
