Value Collection MS24693-S14 Machine Screw 4-40 X 1.5 in

Product Description

The VALUE COLLECTION MS24693-S14 is a 4-40 unified coarse thread machine screw built to MS24693 military fastener standards. It features a flat head profile with a Phillips drive and is manufactured from steel with a yellow cadmium finish for corrosion resistance. The screw measures 1.5 inches in overall length, which also equals the length under the head given its flat head geometry. Grade 3 material classification indicates a carbon steel construction suitable for general mechanical assembly. This fastener is installed by machinists, maintenance technicians, and assembly professionals across aerospace, electrical, and industrial applications.

The MS24693-S14 is used in applications requiring a low-profile, flush-mount fastener in a 4-40 threaded hole. The flat head countersinks into the mating material, keeping the fastener surface flush. Typical install scenarios include panel mounting, instrument enclosures, electronic chassis assembly, and light mechanical assemblies where a Phillips driver is the standard tool. The yellow cadmium finish provides a base level of corrosion protection suitable for controlled environments. This screw ships in multiples of 100 per order minimum.

Key Features

• 4-40 unified coarse thread for compatibility with standard 4-40 tapped holes
• Flat head with Phillips drive for flush countersunk installation
• Steel construction with yellow cadmium finish for corrosion resistance
• Grade 3 carbon steel material classification
• Meets MS24693 military fastener standard
• 1.5-inch overall length with no washer face

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 4-40 x 1.5-inch flat head Phillips machine screw conforming to the MS24693 fastener standard.

Installation Notes

Installation is performed with a Phillips screwdriver or Phillips-bit driver sized for a number 4 screw. Ensure the mating material is properly tapped or threaded to 4-40 specifications before driving the fastener. Countersink the receiving hole to match the flat head angle to achieve a true flush mount. Do not over-torque, as the 4-40 thread size and Grade 3 steel have defined shear limits for light-duty assembly work.
