Burndy TN186F INSULUG Nylon Fork Terminal, 22-18 AWG, #4-6 Stud, 100-Pack

The Burndy TN186F is a nylon-insulated fork terminal engineered for 22-18 AWG conductors and sized for a #4-6 stud. Part of Burndy's INSULUG™ terminal line, this fork-style connector uses an open-tongue design that provides faster installation than closed-ring alternatives, since the mounting screw does not need to be fully removed to seat the terminal. Each unit ships in a 100-pack, making it a practical choice for electricians, panel builders, and maintenance crews who need a reliable supply of insulated terminals on hand for repetitive wiring and termination tasks.

Key Features

  • Wire Range: Designed for 22-18 AWG conductors, allowing a secure crimped connection on smaller-gauge wire.
  • Stud Size: Sized for a #4-6 stud, matching common terminal block and equipment mounting hardware.
  • Fork Design: Open fork tongue allows the terminal to be installed or removed without fully backing out the mounting screw, speeding up wiring and re-termination work.
  • Insulated Construction: Nylon insulation covers the crimp barrel, providing electrical insulation and strain relief at the termination point.
  • Trade Line: Part of Burndy's INSULUG™ family of insulated terminals.
  • Pack Quantity: Supplied in a 100-pack, providing enough terminals for larger wiring runs, panel builds, or ongoing maintenance stock.

Technical Specifications

  • Pack size (unit): 100
  • Trade Name: INSULUG™

Typical Applications

  • Electrical Wiring and Termination
  • Control Panel and Terminal Block Wiring

Why Burndy?

Burndy's INSULUG™ nylon fork terminals combine an insulated crimp barrel with a fork tongue designed for faster, more efficient installation on 22-18 AWG conductors and #4-6 stud hardware. For electrical professionals who need consistent, dependable terminations across large wiring jobs, the TN186F's 100-pack quantity keeps a reliable supply of Burndy terminals on hand for both new installations and ongoing maintenance work.

Burndy TN186F – Frequently Asked Questions

1) What wire size does the Burndy TN186F fork terminal take?
The TN186F is sized for 22-18 AWG stranded or solid conductors. Anything heavier than 18 AWG won't seat properly in the crimp barrel, and wire finer than 22 AWG risks a loose crimp, so stay inside that range for a reliable termination.
2) What stud or screw size does this Burndy fork terminal fit?
It's built for a #4-6 stud, which covers the screw sizes used on most control-panel terminal blocks and small equipment terminals. If your block uses a #8 or #10 screw, the fork tongue is too narrow and you need a larger terminal.
3) Should I use a fork terminal or a ring terminal on my panel wiring?
The fork (open tongue) on the TN186F slides in around a partly loosened screw, so you never have to back the screw all the way out. That saves real time on a panel with a hundred terminations and makes re-termination easier later. A ring terminal is the better choice where the connection sees vibration or where a code or spec requires a captive connection, since a ring can't slip off if the screw backs out.
4) Is the crimp barrel on the TN186F insulated?
Yes, nylon insulation covers the crimp barrel and gives strain relief where the wire enters the terminal. Nylon holds up to handling and abrasion better than vinyl, which matters when you're stuffing a lot of conductors into a wireway.
5) Is the Burndy TN186F the same as an INSULUG terminal?
Same thing. INSULUG is Burndy's trade name for its insulated terminal line, and TN186F is the fork-tongue member of that family for 22-18 AWG wire on a #4-6 stud. If a drawing or bill of material calls out an INSULUG nylon fork terminal in that wire range, TN186F is the part number to order.
6) Do I need a special crimp tool for these Burndy nylon fork terminals?
It's a crimp-on terminal, not a screw-down lug, so you need an insulated-terminal crimping tool with a die matched to the 22-18 AWG range (typically the red-coded nest on a standard insulated crimper). Pliers will not produce a repeatable crimp and the nylon barrel will deform instead of compressing onto the conductor.
7) How many terminals come in a pack of Burndy TN186F?
Each pack is 100 pieces. That's a normal MRO shelf quantity for a shop doing repetitive control wiring, so one pack typically covers a panel build with spares left over rather than being a single-job buy.
8) Where can I get the manufacturer spec sheet for the Burndy TN186F?
Burndy publishes a spec sheet for the TN186F on the Hubbell document site at hubbellcdn.com/specsheet/BRDY-TN186F-SPEC-EN.pdf. That's the document to attach if a submittal package needs manufacturer data for the terminal.
