Value Collection MS24693-C93 Machine Screw 1/4-20 Flat Head

Product Description

The VALUE COLLECTION MS24693-C93 is a 1/4-20 flat head Phillips machine screw manufactured to the MS24693 military fastener standard. It measures 7/16 inches in overall length and is machined from grade 18-8 stainless steel, providing corrosion resistance suitable for both indoor and outdoor applications. The flat head profile allows the screw to sit flush with or below the mounting surface when installed in a countersunk hole. This fastener is used by electricians, HVAC technicians, plumbers, and general trade professionals wherever a flush-mount, corrosion-resistant threaded fastener is required. At 0.006 pounds per unit, the screw is lightweight and suited for panel, bracket, and enclosure assembly work.

This screw is used in light- to medium-duty fastening applications across residential and commercial trade work. Common install scenarios include electrical enclosure assembly, HVAC equipment panel attachment, plumbing bracket mounting, and general sheet metal or fabricated component assembly. The 1/4-20 unified coarse thread is one of the most widely used thread pitches in inch-system fastener applications, making this screw compatible with a broad range of tapped holes and threaded inserts across equipment types. It is sold in minimum order quantities of 100 pieces per package.

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 1/4-20 flat head Phillips machine screw in grade 18-8 stainless steel per the MS24693 fastener standard.

Installation Notes

Installation is performed by any trade professional requiring threaded fastening at the 1/4-20 size. Ensure the receiving material has a properly sized and tapped 1/4-20 hole, or use a matching threaded insert. For flush mounting, countersink the hole to match the flat head angle before driving the screw. Use a correctly sized Phillips bit to avoid cam-out and head damage, particularly in stainless steel, which is susceptible to galling if driven at excessive speed.
