Value Collection 5024MSF Machine Screw 1/2-13 X 1-1/2 in Flat Head

Product Description

The VALUE COLLECTION 5024MSF is a flat head slotted machine screw sized 1/2-13 UNC by 1-1/2 inches overall length. Manufactured from steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional and material consistency. The flat head countersinks flush with the mating surface, making it well suited for applications where a low-profile fastener is required. This screw is driven with a standard slotted screwdriver. It is a general-purpose industrial fastener installed by millwrights, maintenance mechanics, and assembly technicians across a wide range of equipment and structural applications.

This fastener is used in general mechanical assembly, equipment maintenance, and fabrication where a 1/2-13 UNC thread form and flush-mount head are required. The zinc coating provides basic corrosion resistance suitable for indoor and light-duty environments. Overall length measurement is taken from the top of the head to the tip of the screw, measuring 1-1/2 inches. No washer is included or required under the head for standard installation.

Key Features

• 1/2-13 UNC thread size for broad hardware compatibility

• Slotted drive accepts standard flat-blade screwdrivers
• Steel construction with zinc-plated finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional standards
• Overall length of 1-1/2 inches with no-washer head style

Compatibility

Designed for general mechanical and industrial assembly applications requiring a 1/2-13 UNC coarse-thread flat head machine screw in steel with zinc plating.

Installation Notes

Installation is performed using a flat-blade screwdriver or slotted bit driver sized appropriately for a 1/2-inch fastener. A properly sized countersunk hole is required in the mating material to allow the flat head to sit flush. Ensure threads in the receiving material or nut are clean and free of debris before driving. Do not overtighten, as this can strip the slotted drive recess or damage the mating threads.
