Frequently asked questions
What is the K2 Systems TB 28/15 M10x40 hammer head bolt?
The TB 28/15 M10x40 is a hammer head bolt (T-Bolt) made of stainless steel from K2 Systems with an M10 thread, 40 mm length and a head shape of 28/15 mm. It serves as a connecting element that is inserted into the groove of compatible mounting profiles and securely fixed by twisting.
What is a hammer head bolt used for in PV assembly?
Hammer head bolts connect components such as module clamps, end caps or profile connectors to the support profiles of a solar substructure. The hammer head is placed in the profile groove and tightened with a nut – this creates a resilient connection without drilling through the profile.
Why is the screw made of stainless steel?
Stainless steel is corrosion-resistant and permanently withstands moisture, rain and changing weather conditions outdoors. This makes the screw suitable for long-term roof and open-area installations where the connecting elements are exposed to weathering for decades.
What does the head shape 28/15 mean?
The specification 28/15 describes the dimensions of the hammer head in millimeters (28 mm x 15 mm). These dimensions determine which profile groove the screw fits into and how large the contact surface for the form fit in the profile is.
