I have a second hand Hilti gun (Hilti DX 36M), It didn't work. Can I take this tools to you for repairing.

Does a metallic sprinkler pipe that vertically penetrates floors within a stairwell require firestopping? Is there a point of sealing the pipe opening if smoke and fire can spread through the actual open stairwell?

Hi, I have a question about Hilti weld strength increase for Round and Rectangular HSS sections when there is bending moment on the section (refer to highlighted in attachment) Questions: As per AISC 360-22 the directional strength increase factor does not apply to rectangular HSS shapes. However, Hilti Profis applies the i...

Hello, I was wondering about the best practices for tooling firestop sealants. Specifically, is there an engineering preference for using a spatula versus fingers, and for applying with soapy water versus dry? Are there technical advantages to one method over the other in terms of performance or are the differences generally n...

I am looking into reviewing a situation where threaded rod anchors were installed into concrete using the HIT HY270 in lieu of the HY200. I understand that the HY270 is intended for masonry as the base material. Can you direct me to information confirming if this is an acceptable application or not, and if so, where I can find...

Based anchor classification, there are two types of mechanical torque-controlled expansion anchors, a sleeve anchor and wedge anchor. Is the HSL4 anchor classified as a expansion torque-controlled sleeve anchor or expansion torque-controlled wedge anchor? The ICC-ES ESR-4386 classifies the HSL4 anchor as a torque-set, sleeve...
