Large diameter tapcon with debris reservoir end or tip |
摘要 |
A masonry anchor is provided with a reaming portion which includes recessed portions for defining reservoir regions for accumulating debris generated by the reaming operation when the anchor is installed within a masonry structure. The accumulation of the debris within the reservoir regions reduces torsional friction and installation torque characteristic of the anchor installation operation. Masonry anchors which are self-tapping or self-threading and which do not have reaming portions operatively associated therewith can also have such recessed reservoir structure defined thereon for such similar dust and debris accumulation and discharge purposes.
