Our alloy concrete fastener with stainless steel pin (mush pin) offers a tamper-proof, permanent solution for securing survey boundary discs and control markers. Ideal for use in concrete, masonry, brickwork, and natural stone, it ensures your survey reference points stay firmly anchored over time.
The internally tapered body expands when driven by the pre-assembled, passivated stainless steel nail, providing exceptional grip in all solid masonry surfaces.
