Steel bolt gate hinge set designed for hanging pipe gates and panel gates. These are strong steel hinges that can handle the demands of local farm use. 5/8" x8" zinc plated. SWL 150 lbs. This steel bolt gate hinge can be adapted for the larger corner wooden posts (if necessary) by using a portable/electric drill with a hole bit large enough to countersink the last nut and washer inside the hole. Then you can use a box end wrench to hold the steel bolt gate hinge while you fasten the nut securely with a socket driver.
