Fastener Specifications

The Kerr Lakeside button head socket cap screw uses a 3/8-16 UNC coarse thread with a 1/2 inch length. A 7/32 inch hex socket drive installs the fully threaded shank. Black oxide finish protects the alloy steel from corrosion. Fifty pieces are supplied per package.

Thread Compatibility

The single specification that decides fit is the 3/8-16 UNC thread pitch. It matches only tapped holes or nuts cut to that exact diameter and count. Mismatched threads will bind or strip, so verify the mating part before purchase. The fully threaded shank engages the full 1/2 inch depth.

Installation Requirements

A 7/32 inch hex key or driver bit is required to drive the socket head. The low-profile button head sits 0.199 inches tall, clearing tight spaces where a standard hex head would interfere. Alloy steel construction handles high preload without stretching. No washers or locking compounds are included.

Questions about this item

How deep will the 3/8 -16 thread engage when the 1/2 in length is fully seated?

The minimum and actual thread length are both 1/2 in, so the full shank engages when the screw bottoms out.

What size hex key fits the 7/32 in socket drive on these button head screws?

A 7/32 in hex key matches the drive size exactly and provides full torque transfer without rounding.

What is the head height clearance above the mating surface once the screw is tightened?

The button head sits 0.199 in tall, leaving a low-profile finish suitable for flush or counterbored holes.
