What it is and who it fits
Kerr Lakeside button-head socket cap screws come in an 8-32 by three-quarter inch size with a black oxide finish. The pack contains one hundred pieces of alloy steel fasteners that meet ASTM A574 and ANSI B18.3 standards. They suit maintenance technicians and assembly lines that need a consistent supply of coarse-thread hardware. Builders who require a different thread pitch or a longer shank should look elsewhere.
Behaviour under sustained load
Each screw is hardened to a Rockwell C rating of 38 to 43 and offers a minimum tensile strength of one hundred eighty thousand pounds per square inch. The full-thread design distributes clamping force along the entire length during prolonged vibration. Hex drive sockets transmit torque without cam-out when the joint is retightened repeatedly. Applications that demand higher shear ratings or a finer thread series will not be satisfied by this specification.
Thermals noise and power draw
As passive mechanical components these screws generate no heat, sound or electrical draw during installation or service. The black oxide coating provides mild corrosion resistance without adding measurable mass; the total pack weight is zero point four seven pounds. RoHS compliance confirms the absence of restricted substances. Environments that require plated or stainless finishes for chemical exposure are outside the intended use case.

Questions about this item
How much heat does the 180000 psi alloy steel generate during continuous fastening?
These are passive fasteners with no moving parts, so they produce no heat during use.
What drive tool is needed for the hex socket on these 8-32 screws?
A 3/32 inch hex key or hex driver bit engages the internal socket drive.
Will the coarse UNC threads engage older tapped holes cut to the same 8-32 standard?
Yes, the 8-32 UNC coarse thread matches legacy 8-32 tapped holes.
