Precision fastener for threaded assemblies

Kerr Lakeside 25C62KCS socket head cap screws come in a 100-piece pack. Each screw measures 1/4-20 x 5/8 in. and features a black oxide finish. The hex socket drive accepts a 3/16 in. key. They are made from alloy steel for reliable clamping force.

Suited for maintenance and fabrication tasks

Mechanics and fabricators who need fully threaded UNC coarse fasteners will find these match the requirement. The right-hand threads and 0.25 in. head height fit standard inch-pattern holes. Buyers needing metric threads or a different drive style should look elsewhere.

1/4-20 UNC thread with 5/8 in. length

This specific diameter and pitch combination determines fit in existing tapped holes. The 5/8 in. thread length provides full engagement through the material thickness. Verify the thread callout before ordering to ensure compatibility.
