    Hex Cap Screws, Grades 2

    A hex cap screw is a six-sided bolt with a trimmed hex head and a washer face on the bearing surface. Informally, it is also called a Finished Hex Bolt. Hex cap screws have tighter tolerances than standard bolts of the same size, and so are often used where precise tolerances are needed. The standard hex screw specifications include ASTM A449 and SAE J429 Grade-2.

    Hex Tap Bolts

    The major distinguishing feature of hex tap bolts is that they are always fully threaded from under the head to the tip, no matter the size. Other features, such as chamfered point or washer bearing surface under the head, may be present, or may not. Tap bolts are meant to be used nuts to secure two objects together, but they also will fully seat into a tapped hole to secure one material to a base material.
    They are available in Grade 2, Grade 5, and in Stainless Steel.
