Leader-Fastener® T-Head Bolts, also knows as Hammer Head Bolts, T-Slot Bolts and Tank Strap Bolts, have either a Tee or square shaped head. Normally they are are installed into a hole with a tee shaped slot so that the head of the bolt can sit flush, and the shape of the bolt resists turning while tightening.
Metric DIN 186 T Bolts have a T-shaped head which can fit into a pre-cut slot or can be easily gripped by a standardwrench. DIN 186 T-Head bolts are partiallythreaded along their shank, the thread length depending primarily on the lengthof the bolt. The square neck right beneath the head seats into the hole, preventing the bolt from rotating in its hole. T-head bolts can be used for most applications involving tensioning and clamping.
