STUD BOLTS
DAN-LOC produces alloy steel stud bolts in 3/8-inch through 4 3/4-inch diameters and to any length. Our DAN-LOC tap-end stud bolt combines a cold forming process with a superior design incorporating a thread shoulder for uniform depth of engagement. SPECIAL COATINGSWe also can furnish a wide range of special coatings to prevent corrosion. Whether it’s cadium, zinc plating, Teflon and Xylan flurocarbon or other coatings, all protect our products from conditions and environments that uncoated bolts can’t withstand.
