Hex Tap Bolt

Hex Tap Bolt Description

A hex “tap” bolt is a term used to describe a fully threaded hex bolt. Many of our customers will use the terms “Hex Tap Bolt” and “Fully Threaded Hex Cap Screw” interchangeably. Remember, that in the U.S., a “bolt” is a fastener that is designed to be used with a nut. A “screw” is a fastener that is designed to be able to be installed by tightening the head.

A hex tap bolt should be assembled with a nut and the nut should be turned to tighten the assembly. A fully threaded hex cap screw can be used with or without a nut (tapped hole) and can be assembled by turning the head or the nut during assembly. Typically, in our industry, if someone orders a hex bolt you can always supply a hex cap screw. If a hex cap screw is ordered you cannot just supply a hex bolt without first getting the customers approval.

Hex Tap Bolts on the other hand are fully threaded regardless of size. This means the threading goes from the tip all the way to the underside of the head of the bolt. They have a weaker tensile strength but the extended threads make them more suitable for situations where hex cap screws may not function well. Hex tap bolts are available in diameters 1/4″ and up.
