3M 7000133647 Block Fork Terminal Awg 12-10 Stud Size 8

Product Description

The 3M 7000133647 is a vinyl insulated block fork terminal designed for secure wire termination in terminal block applications. It accepts wire sizes from 12 to 10 AWG and fits a stud size 8 fastener. The flat-sided block fork profile is engineered specifically to seat flush against the barrier portion of a terminal block, providing the same pull-out strength as a standard fork terminal while maintaining a clean, organized wiring layout. Electricians and panel wiring technicians rely on this style of terminal where space management and reliable contact inside barrier strips are required.

This terminal is suited for residential and light commercial electrical wiring, control panel assembly, and any application where connections must be made at a terminal block rather than a free-standing stud. The 12-10 AWG wire range makes it compatible with common branch circuit and control wiring conductor sizes. It is sold in packs of 10, with a minimum order quantity of 10 packs per case.

Key Features

• Flat-sided block fork profile seats flush against terminal block barriers without lifting or tilting
• Accepts 12-10 AWG wire range for common control and branch circuit conductors
• Stud size 8 fitment for standard terminal block fasteners
• Vinyl insulation provides electrical protection at the barrel and conductor entry point
• Equivalent pull-out strength to standard open fork terminals

Compatibility

Designed as an OEM-style replacement and general-use block fork terminal for barrier-style terminal blocks accepting stud size 8 hardware and 12-10 AWG conductors.

Installation Notes

Installation is typically performed by licensed electricians or qualified panel wiring technicians. De-energize and lock out the circuit before terminating or removing conductors, following applicable NEC lockout-tagout requirements. Use a properly calibrated ratcheting crimper sized for 12-10 AWG vinyl insulated terminals to ensure a gas-tight crimp. Do not over-torque the terminal block screw, as this can deform the fork and reduce contact integrity.
