Countersink Hole Tolerancing at Mary Huntsberry blog

Countersink Hole Tolerancing. Countersink holes are conical recesses created on the surface of a material to accommodate the heads of fasteners. This article will explore what countersink holes are, their uses, and how to apply ansi standards to create precise, flush finishes in manufacturing. The easiest tool to use, assuming the tolerances aren’t too tight, is a. A countersink consists of a conical hole that is coaxial to a cylindrical hole, where the angle of the cone is determined by the fastener to be used. They serve the purpose of allowing the fasteners to sit flush or below. Generally speaking, such a tolerance should be: When using positional tolerancing, which is usually the most appropriate way for hole patterns, you can use the below method. Countersinks can be measured by many different gauges. The above calls out a 0.25dia pilot hole diameter, 0.5dia countersink diameter with a bilateral tolerance of 0.005, and a 90 deg countersink angle. Now, let’s solve an ansi based problem — we’ll use a table to determine how to properly make the call out.
