RA18-6FL Fork Terminal #6 Stud 16 AWG

The Sta-Kon RA18-6FL is a nylon-insulated fork terminal built for 16 AWG wire and a #6 stud. It carries a 600 V rating and a maximum operating temperature of 221 degrees F. The brazed seam and tin-plated copper contact provide a secure crimp connection for automotive or industrial wiring tasks.

Before ordering check wire gauge and stud size

Verify that your conductors are 16 AWG and that the mounting hardware uses a #6 stud. The terminal accepts a maximum wire size of 16 AWG and the tongue length measures .4 in. Confirm the barrel length of .46 in fits your crimp tool and that the partial insulation coverage meets your insulation requirements.

Build quality and daily implications

The nylon insulation resists heat up to 221 degrees F and the tin finish protects the copper contact from corrosion. A brazed seam prevents the barrel from splitting under stress while the insulation grip style holds the wire jacket firmly. The fork tongue allows quick installation on a #6 stud without removing the fastener completely.

Not for buyers needing larger wire gauges

This terminal is limited to 16 AWG conductors and a #6 stud pattern. Installers working with heavier cable or alternative stud dimensions must select a different part number.

Questions about this item

What comes in the package and is a crimp tool included?

The terminal is sold individually; a compatible crimp tool for the insulation-grip barrel must be purchased separately.

How do I choose between the compatible Grainger part numbers 3KH46, 3KH52 and 4XMR5?

All three Grainger numbers reference the same #6 stud, 16 AWG fork terminal; select the one that matches your existing inventory code.

What does the 221 °F temperature rating mean for under-hood use?

It allows continuous operation in engine-bay heat up to 221 °F without insulation degradation.
