3.2.12 STUD FASTENERS FOR ATTACHMENT TO STEEL
3.2.12.1 PRODUCT DESCRIPTION
The Hilti threaded stud program is for use with Hilti powder-actuated tools to provide a fast and reliable solution for making attachments to steel base material in lieu of through bolting , screw fastening , or stud welding . Threaded studs are available in SAE 316 stainless steel equivalent corrosion resistance or carbon steel to meet a wide range of application requirements when making fastenings to steel 3 / 16 " and thicker . The X-EW6H and X-EW10H threaded studs are hardened fasteners with a unique knurled shank design for improved penetration and high tension and shear values in ASTM A36 and higher grades of steel . Thread diameters are 1 / 4 ", 3 / 8 ", and 8 mm with thread lengths ranging from 3 / 8 " to 1-1 / 2 ".
