8mm x 45mm - 100pc Hookbolt Sleeve Anchors Zinc Yellow

Hookbolt Sleeve Anchors are used to anchor into hard and lightweight solid masonry materials inluding concrete, brick and blocks. The Hookbolt Sleve anchor is inserted into a 8mm hole drilled into concrete and once the head is turned, the working end of the anchor is pulled to expand and secure itself into the masonry, leaving a protruding hook. Please see attached table on drill size and hole depth.
