Product Information

The Excalibur Screwbolt is the first universal anchor primarily designed for use in all spectrums of industry. Its unique twin helical thread ensures high tensile-shear-close to edge and centre spacing safe loadings. Screwbolt’s versatility enables it to be an alternative to virtually all the traditional masonry fasteners currently available – only need one fixing type!

Secure fixing – The Twin helical thread gives secure grip throughout the full embedment
Fast – 30° helix angle for fast insertion with power or hand tools (eg. 3 turns= 40mm embedment on 8mm)
Grip/Pullout – The Wide pitch produces high strength grip without distressing surrounding substrate/material and the Deep thread engagement results in high performance
Edge fixing – No expansion by the bolt provides ability for close to the edge fixing
Reusable – Self tapping of thread into substrate allows for removal and replacement

With ISO9001: 2015 approval incorporating Design Status, our qualified engineering staff are able to offer a completely free of charge engineering service and are available to assist with part selection, custom design, application requirements, material selection and more.

Applications are discussed in-depth, first-off design data and drawings are submitted for approval to ensure our customers are provided with the correct design, first time. However, on those rare occasions when modifications are necessary, our no-tooling process and flexible manufacturing procedures means the production of prototypes is easily and economically achieved without onerous tooling charges and long lead times.
