Value Collection MS24693-C301 Flat Head Machine Screw

Product Description

The VALUE COLLECTION MS24693-C301 is a flat head Phillips machine screw built to the MS24693 military fastener standard. It features a 1/4-28 unified fine thread form and measures 1-3/8 inches in overall length. The head is countersunk flat style, driven with a Phillips bit. The screw is machined from 18-8 stainless steel and finished with a passivated surface treatment to reduce corrosion. Machinists, maintenance technicians, and aerospace or industrial assembly workers install this screw where a flush-mount fastener is required in corrosion-resistant applications. No washer is included or required under the head.

This screw is suited for general industrial, MRO, and light aerospace assembly applications where a standardized military-specification fastener is called out. The 1/4-28 fine thread pitch provides good holding strength in metal substrates and resists loosening under vibration. The passivated 18-8 stainless steel construction makes it appropriate for environments with moisture exposure or where galvanic compatibility with stainless components is needed. Sold individually per package, with a minimum order quantity of 10 pieces.

Key Features

• MS24693 military fastener standard compliance for consistent dimensional control
• 1/4-28 unified fine thread for strong pull-out resistance in metal

Compatibility

Designed as a direct replacement or general-use fastener for assemblies calling out the MS24693 fastener standard in 1/4-28 x 1-3/8 inch flat head Phillips configuration.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians using a Phillips screwdriver or bit driver sized for a 1/4-inch fastener. De-energize and lock out any equipment before fastener replacement in live assemblies. Do not overtighten stainless steel fasteners into stainless threads without anti-seize compound, as galling can occur. Verify mating thread condition and countersink geometry before installation.
