Description
OEX ACX0103FE/50 Copper Zinc Plated Flared End Cable Lug 6 B&S REF 16 6 with 6mm Stud Hole Pack of 50
The OEX ACX0103FE/50 is a copper cable lug with zinc plating, flared end barrel design and 6mm stud hole, sized for 6 B&S wire. Reference number 16 6 indicates a 16mm barrel inner diameter and a 6mm stud hole diameter. The barrel is secured to the stripped cable end by crimping or soldering, and the ring end bolts to any M6 bolt, stud or terminal. Supplied in a bulk pack of 50 with a one year warranty, suited to auto electricians, workshops and trade use.
Product overview
The ACX0103FE/50 uses a flared end barrel design where the cable entry end of the barrel is slightly expanded outward, acting as a guide funnel when inserting stripped cable strands. This guides all strands into the barrel smoothly during installation, reducing the chance of stray strands being crimped outside the barrel. A stray strand outside the barrel reduces the effective cross section of the connection and creates a potential failure point. The flared entry improves connection integrity and consistency compared to a plain barrel lug, particularly when working with larger gauge cables.
At 6 B&S (approximately 13.3mm²), this lug suits higher current applications than the 8 B&S ACX0100, covering dual battery main cables, large inverter connections, solar panel strings and high current starter circuits. Copper construction provides excellent electrical conductivity and the zinc plating adds corrosion resistance for automotive and marine environments. The bulk pack of 50 is practical for workshops and auto electricians working across multiple jobs.
Features and benefits
Flared end barrel for improved installation integrity: The outward flared barrel entry guides cable strands in during installation, reducing missed strands and improving connection consistency compared to a plain barrel lug, particularly on larger gauge cable.
6 B&S wire capacity: The 16mm barrel suits 6 B&S wire (approximately 13.3mm²), handling higher current loads than the smaller 8 B&S ACX0100 and suited to dual battery systems, inverter connections and high current starter circuits.
Copper with zinc plating: Copper provides excellent electrical conductivity and the zinc plating adds corrosion resistance for automotive and marine environments.
6mm stud hole: The ring end fits M6 bolts, studs and terminals with 6mm connections, covering battery terminals, fuse panels and distribution blocks.
Solder or crimp termination: Compatible with both crimping and soldering, giving installers flexibility based on available tooling and preference.
Reference 16 6: Standard industry reference where 16 denotes the barrel inner diameter in millimetres and 6 denotes the stud hole diameter in millimetres.
Bulk pack of 50: Suited to workshops, auto electricians and multi project trade use where high volumes of lugs are required.
One year warranty: Covered by a one year OEX warranty.

Frequently asked questions
What is a flared end barrel and why does it matter? A flared end lug has the cable entry end of the barrel slightly expanded outward, like the bell of a trumpet. When inserting stripped cable strands, the flare acts as a guide funnel directing all strands into the barrel smoothly. A plain barrel lug has a straight cut entry that can catch stray strands outside the barrel during insertion. Stray strands crimped outside the barrel reduce the effective cross section of the connection and create a potential failure point. The flared end reduces this risk, improving connection integrity and consistency.
How does 6 B&S differ from 8 B&S for current capacity? 6 B&S is approximately 13.3mm² cross section while 8 B&S is approximately 8.4mm². The larger cross section of 6 B&S allows the cable to carry more current with less voltage drop and heat generation. 6 B&S is used for heavier loads including dual battery main cables, large inverter connections, solar panel strings and high current starter circuits. Confirm the current requirements of your application against the cable and lug rating before purchasing.
Should I solder or crimp these lugs? Crimping with a calibrated or hydraulic lug crimper is the preferred method for professional automotive and marine electrical work, producing a consistent, cold welded connection. Soldering provides a sound connection when carried out correctly with appropriate heat and flux, but is more dependent on technique. For bulk workshop use, a ratchet or hydraulic crimper is the practical choice for consistent results across multiple terminations.
What does the reference number 16 6 mean? The two numbers in the reference indicate the barrel inner diameter and the stud hole diameter, both in millimetres. REF 16 6 identifies a lug with a 16mm barrel suited to 6 B&S wire and a 6mm stud hole suited to M6 bolts and studs. Using the reference number ensures you select the correct lug for your wire and stud size combination.
How does the ACX0103FE/50 compare to the ACX0100? The ACX0100 (REF 10 6) is an 8 B&S lug with a 10mm barrel and 6mm stud hole, supplied in a 10 piece pack. The ACX0103FE/50 (REF 16 6) is a larger 6 B&S lug with a 16mm flared end barrel and 6mm stud hole, supplied in a 50 piece bulk pack. Select based on your cable size and quantity requirements.
