Description
This hexagonal crimping tool is manufactured specifically for crimping the 4.7mm Lucas-style bullet connectors onto 16 AWG and 18 AWG stranded wires, as commonly used on vintage British automobiles and motorcycles. When used correctly, the crimping tool provides a secure and permanent crimp, saving time and frustration versus soldering. Ideal for wiring harness construction and repair.
The crimping tool has a ratcheting mechanism that ensures a secure and successful hexagonal crimp when fully closed over the narrowed waist of the 4.7mm Lucas-style bullet crimp-type connector. Designed for use with 16 and 18 gauge stranded wires. Not recommended for use with solid-core wiring.
The hexagonal crimp is a superior way of fixing bullet connectors to stranded wiring compared to a crude flat crimp, where the bullet connector becomes compromised by the collapse of the metal structure. The hexagonal crimp offers an even grip on the wiring when the correct gauge of wire is used with the appropriately sized bore of the Lucas-style 4.7mm OD bullet connector. Minimum recommended wire size for crimping with this tool is 18 gauge.
The 1mm bullet connectors are compatible with 18 gauge stranded wires, while the 2mm bullets will accept the larger diameter 16 gauge stranded wires. It is critical the crimp is placed at the narrowed waist of the bullet connector to ensure adequate conductivity between the wire and bullet. Generally about 7-8mm of insulation is stripped from the wire, resulting in a visible tuft of copper wiring above the tip of the connector. Tinning stranded wiring is not recommended when hexagonally crimping the bullet connector.

Very highly recommend this tool. Price is staggering, but that is the cost of quality tool that actually works. This tool is indeed professional quality. You will not regret buying this tool. There is no other tool sold that can give original hex crimp like factory used. The hex crimp holds wire better than the less costly pinch crimper that is on the market. Way easier than soldering. Works especially good for replacing broken alternator wire bullets.
Using tool takes a little practice. Depending on bullet size & conductor size you can over-crimp & distort bullet.
Too thin of conductor for the bullet in hand the wire will pull out.
It is important to understand the relationship between bullet inside diameter, wire diameter & how much to crimp bullet. Bullets for sale here at Bonnie Shop are sized for Triumph 14 strand wire, or AWG 16,18 size (C314 bullet). Other size wire needs bullet with larger or smaller ID hole. 4 sizes of bullets are made for AWG from 20 through 12 gauge strand wire.
Using crimper, you strip wire, place conductor into fully into bullet. Place recess of bullet in crimper jaws. Jaws are sized just right for recess.
Squeeze crimpers until bullet is crimped & conductor is held tight. The ratchet on pliers keeps jaws from opening until jaws are fully closed very tightly, then ratchet auto releases.
However, this formula only works with specific wire size in specific size bullet. C314 bullet with Triumph 14 strand or 18 AWG wire. 16AGW it tends to over crimp.
This is where practice comes in. Get several spare bullets. On the bench practice with Triumph 14 strand if possible. At least practice with both 16&18AWG wire & get the feel of it. Try to pull wire out hard as you can. It should break wire before it pulls out. I find with 16g I stop crimp just before auto release. You can turn knob & release ratchet whenever you want or need to.
Auto release works good with Triumph 14 strand & C314 connectors sold here at Bonnie Shop
Once you get the hang of it you can make perfect crimps every time very quickly that will never pull off. It conductor sticks out past bullet tip, simply cut it off flush.
Triumph 14 strand wire means original Triumph wire that has 14 copper strands inside it. Probably Imperial (British) 18G which is slightly fatter than 18AWG.
Tip, put a few drops of motor oil on all the pivots & moving joints of crimper. Gives it really smooth operation.
