Stop losing your grinder’s spanner nut. The TMR Customs Nut Cupper is the ultimate angle grinder nut holder — it threads directly into your grinder to keep your nut locked down when it’s off the tool. No more digging through drawers, crawling under benches, fighting spiderwebs, or swearing mid-project — this is spanner nut storage done right.

Features:
Holds your spanner nut securely when not in use
Threads directly into your grinder for easy storage
CNC machined for a perfect fit
Built tough from heat treated 4140 steel

The Nut Cupper – because nobody likes a loose nut.
