The 31113 is the 10-12 AWG member of TE's Budget series ring terminal line, a non-insulated circular terminal for #8 studs. Crimp termination on 10-12 AWG wire; the tin-plated copper body is 0.039" (0.99mm) thick and serrated on the barrel to grip the conductor.
Budget vs Solistrand: thickness and wire range
The Budget 31113 at 0.039" (0.99mm) thickness carries a heavier cross-section than the Solistrand 1377172-7 (0.031" / 0.79mm) for 14-16 AWG — the thicker barrel suits the larger 10-12 AWG conductor. The 31113's 0.765" (19.43mm) overall length is longer than the Solistrand 1377172-7's 0.636" (16.15mm), matching the longer barrel needed for the heavier wire.
