Proper Use of GatorJaw Fasteners
It is important that you use the proper length fastener when you're attaching the GatorJaw brackets or any other hardware. The fastener should seat as far into the square threaded groove as possible
without bottoming out.
All stamped GATORJAW brackets are designed for the 1/2" long GATORJAW screw. Any bracket that surface mounts as opposed to mounting into the channel usually will need the 3/4" fastener. When surface mounting brackets, you should always use a 1/8" thick spacer or washer under the bracket to fill the recess in the frame rail. This will allow the fastener to tighten properly and prevent it from vibrating loose.
