The ASTM A563 specification covers the chemical and mechanical requirements for carbon and alloy steel nuts used on bolts, studs, and externally threaded fasteners. The charts below address over tapping allowances for hot-dip galvanized nuts, grade marking requirements, and mechanical requirements.
According to the A563 specification, “The requirements for any grade of nut may, at the supplier’s option, and with notice to the purchaser, be fulfilled by furnishing nuts of one of the stronger grades specified herein unless such a substitution is barred in the inquiry and purchase order”. This is important because some nut grades are not readily available in certain sizes and finishes. Additionally, the specification allows for the substitution of ASTM A194 grade 2H nuts in lieu of A563 grade DH nuts due to the lack of availability of grade DH nuts in nominal sizes 3/4″ and larger.
Hot-dip galvanized nuts must be tapped oversize to allow for the added thickness of the zinc on the threads of the externally threaded fastener. These allowances are addressed in the chart below.
Various nut styles exist and to some degree are determined by their grade. These styles include hex, heavy hex, square, jam, coupling, and sleeve.

Greg German demonstrates spinning and a hydraulic puller tool at the Future of Fixed Anchors II Conference in Red Rocks on April 2, 2016 by removing a wedge bolt. The purpose of this technique is to aid the removal of old climbing anchors in order to reuse the old hole and upgrade to better hardware. Visit https://www.accessfund.org/ffa for the full proceedings of the conference.
Please note that this technique exerts extreme force on the anchor and surrounding rock — “dinner plating” (i.e. a plate of rock fracturing off at the surface of the hole) or compromising the rock in some other way is a possibility when using this technique and will depend on rock type. The best uses of this tool are still being worked out by the rebolting community.
