Rectangular Nuts

Rectangular nuts are useful in many woodworking applications.  Their large surface area reduces embedding into softwoods and are self-locking when the flat side is oriented toward material.  Commonly used in clamping applications and even more commonly in T-Track.

13-M010 1/4-20 Nut fits into most 1/4” Aluminum T-Track's including both Woodpecker and Incra T-Track. It measures 7/16” wide, 1” long and approximately 1/8” thick.

13-M015 ¼-20 Nut is a larger version of the 13-M010 and will only fit the T-Slot in the front of the Incra Twin Linear fence.  It will not fit most ¼” aluminum T-Tracks.

13-M020 5/16-18 and 13-M030 3/8-16 fit into the front slot of the Incra Table Saw Rails.  This can be quite useful for attaching in-feed and out-feed support tables.
