Sold individually – the price shown is for one anchor nut.
Imperial two-lug anchor nuts (MS21047 fixed and MS21059 floating pattern) are riveted behind a panel or bracket to give you a permanent captive thread. Bolts can then be fitted and removed from one side without a spanner on the back, ideal for floor panels, bulkheads, dash panels, undertrays and access covers.
How to choose
The threaded barrel is solid with the base. Use where your holes line up accurately, such as drilled brackets and jigged panels.
The nut can move slightly inside its cage, so the bolt still starts if the holes are a little out of line. The best choice for removable panels and covers.
Match the anchor nut to your bolt: 8-32 (approx. 5/32"), 10-32 UNF (approx. 3/16"), 1/4"-28 UNF, 5/16"-24 UNF or 3/8"-24 UNF.
Fitting
- Drill a clearance hole for the bolt, then use the anchor nut as a template to drill the two rivet holes.
- Fix with countersunk or dome-head rivets from the front.
- Pair with our NAS bolts or UNF cap head bolts.
