The anchor is inserted through the fixture and into a pre-drilled hole, where tightening the nut draws an expansion cone into a metal sleeve. This forces the sleeve to expand against the sides of the hole, creating a strong mechanical lock within the base material.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThis through-fix method allows the fixture itself to act as the alignment guide during installation, improving accuracy and reducing installation time compared to separate anchor systems.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eThru Bolts are widely used in structural steelwork, mechanical installations and general construction applications where secure anchoring into concrete or masonry is required. Their high load capacity makes them suitable for both medium and heavy-duty fixing requirements.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eThe design ensures consistent performance when correctly installed, while allowing immediate load application in many use cases.
