Delta Machinery 36-659 arbor nut assembly is a great addition to any 10" UNISAW(r) or other table saw with 5/8-12 Acme right hand arbor threads
For single blade operations, an arbor nut coupled with a 5/16" x 2-1/2" diameter machined steel flange provides rigid blade stabilization
For stacked dado applications, switch to the separate arbor nut without a flange
Each features a wide knurled grip with hex head for final tightening
