Sta-Kon RE10261MOD LRG NYL INS RNG TRM 6AN BOLT NO10

It is insulated, and the insulation is nylon rather than vinyl. Nylon sleeves hold up better to abrasion and crush during crimping and handling, which is why they are common on larger gauges like this 6 AWG terminal. The nylon covers the barrel only, so the ring tongue itself is bare metal for the connection.

A ring terminal like the RE10261MOD has a closed tongue, so the screw has to come all the way out to remove it, but the connection cannot vibrate loose or slip off the stud. A fork or spade tongue drops on and off under a loosened screw and is faster for service work. For anything permanent, high vibration, or where a loose lug is a safety problem, the closed ring is the one to use.

Yes. A 6 AWG barrel is well past the range of the common red/blue/yellow 22 to 10 AWG hand crimper. Terminating the RE10261MOD takes a heavy duty crimper rated for 6 AWG Sta-Kon style terminals, typically a ratcheting or hydraulic tool with the matching die. Crimping a barrel this size with an undersized tool gives an incomplete crimp and a hot joint.

Order by the Sta-Kon catalog number, RE10261MOD. That single designation covers the 6 AWG barrel, the No. 10 ring, and the nylon insulated body, so there are no finish or size options to pick. Specify it exactly when matching a spec or restocking an MRO bin.

Country of origin on the RE10261MOD is listed as the United States or Mexico. That matters if you are filing domestic preference or trade documentation on a government or institutional order, so note that both origins apply to this part.
