T Head Bolts are made to ASME/ANSI B18.5.2 dimensional specifications. T-head bolts are commonly used in a number of applications, including machine tool clamping fixtures and pipe clamps. The T head configuration enables the head to be placed into a slot and held in place with a 90-degree turn of the head. The thread diameter is equal to the width of the head (and the groove it can be inserted into).
The material and physical properties of Grade 5 screws meet the SAE J429 specifications.
