3.2.11 STUD FASTENERS FOR ATTACHMENT TO CONCRETE
3.2.11.1 PRODUCT DESCRIPTION
The Hilti threaded stud program is for use with Hilti powder-actuated tools to provide a faster and more reliable solution for making attachments to concrete base materials . Threaded studs are available in standard carbon steel . The X-W6 and W10 threaded studs have varying shank lengths to provide more reliable fastenings to standard and high strength concrete . Thread diameters of 1 / 4 " have thread lengths ranging from 1 / 2 " through 1-1 / 2 ". The 3 / 8 " thread diameter has a single thread length of 1-3 / 16 ".
