T Head Bolts
The ACS Curve T Head Bolt is designed to fix masonry support back to the 31/21 Axis Curve Channel, without the need for site drilling or post-fixing. The bolt is inserted into the slot between the lips of the channel and rotated through 90°, engaging with the channel’s curved profile and locking into place ready for ancillary components to be fixed.
