Hex Head Capture Washers And Tabs

These weld-on hex lock rings are meant to hold one end of nut and bolted fasteners, to allow one-tool tightening.   Whether it’s a location that’s not accessible with a wrench or socket or just for convenience.  CNC plasma cut from USA-made 1018 steel currently in 2 offerings to fit  9/16" nuts (13/16" hex) and 5/8” nut and bolt hardware(15/16” hex).   Other sizes also available at request.

We prefer to use these on the nut side and then mark the tightened bolt head and bracket with a paint marker. That way, at a glance, hardware that has loosened up, can be quickly and easily identified if the paint marks no longer line up.

These will vary in thickness of either 3/16” or 1/4” as they are nested between existing parts on sheets being cut (helping us to minimize material waste as much as possible).

These come off the table, the dross cleaned off and the fit verified, some weld prep may be required. 

We also offer a bolt-on style hex lock tab, for those that don’t want a permanent, welded keeper to be used.  Simply drill and tap a hole and bolt the locking tab on.  The bolt-on locking tabs are made from 1/8” USA made 1018 steel, with a 1/4” hole for the retaining bolt.  These accept 5/8” hardware(15/16” hex/wrench/socket size).  Other sizes also available at request  

Using a different size hardware than 9/16" or 5/8”?  Shoot us an email and we can cut whatever other size you need(no smaller than 1/2” hardware, or 3/4” hex).
