T-Bolt Anchor M12 Hammer Head Bolt for Embedded Channel

T-Bolt Anchor M12 Hammer Head Bolt for Embedded Channel

The stainless steel T-bolt, or hammer-head bolt, is designed to slide into and lock inside cast-in embedded channels. This M12 version is matched to C50/30 series channels and is used for the adjustable fastening of curtain wall brackets and steel supports; the M10 version suits the lighter C40/22 channel.

Because the bolt head sits inside the slot and can slide along the channel before tightening, installers gain on-site positional tolerance that helps absorb small differences between the fabricated steel and the designed bracket grid. The same T-bolt family is offered in M10, M12 and M16 thread sizes, so engineers can spec one fixing style across light-duty and heavy-duty channel layouts on the same facade.

Installation & Usage

The hammer head is dropped sideways into the channel slot, rotated to lock under the channel lips, and slid along to the required bracket position. The curtain wall bracket or steel support is then threaded onto the projecting stud and aligned, before the nut is tightened to the values given in the project documentation. Stainless surfaces are wiped after installation to remove finger marks and grout splashes.

Quality Assurance

Every T-bolt is 100% inspected before shipment for thread accuracy, head dimensions and surface condition. Material test certificates are available on request to support project specifications.
