2x4 Screw Jigs

thingiverse

This collection of jigs makes it easy to precisely position two 2x4s together by drilling two precise holes in the right place. Some jigs are designed specifically for joining two ends, while others connect one end to the middle of another.\r\n\r\nThe tiny 1/8" diameter holes can accommodate construction screws perfectly but also serve as pilot holes for larger drill bits. The photos provided show boards with enlarged holes drilled for use with 1/4" hex bolts.
