Ring terminal connector BLOW 43-009# insulated screw 3.2 mm stud for 4.3 mm cable

The BLOW ring terminal connector 43-009# is an insulated screw-type lug designed to create secure, low-resistance connections in electrical installations. It accepts wire with a 4.3 mm outer diameter and fits a 3.2 mm screw or stud, providing a compact termination that insulates the conductor while allowing reliable mechanical fastening. This connector is intended for applications requiring a ring-style terminal with screw mounting and is compatible with common copper and tinned copper conductors when crimped or soldered according to standard practices.

Advantages

The insulated construction reduces the risk of accidental short circuits and provides basic environmental protection for the conductor termination. A 3.2 mm screw/stud aperture ensures compatibility with standard fasteners used in small electrical panels and automotive connections. The ring shape offers a dependable mechanical and electrical contact area that remains secure under vibration when properly installed. The compact design makes it suitable where space is limited and a firm screw attachment is required.

Suitable for

• Grounding connections in small electrical equipment
• Battery terminal attachments and auxiliary power lines
• Automotive and motorcycle electrical repairs and modifications
• Control panels, junction boxes and terminal strips with 3.2 mm studs

Key specifications

• Insulation type: insulated ring terminal
• Screw/stud diameter: 3.2 mm
• Compatible cable outer diameter: 4.3 mm
• Contact shape: ring lug for screw fastening
• Typical conductor compatibility: solid and stranded copper conductors

How to use

Strip the cable to expose the conductor length recommended for this terminal, insert the conductor fully into the barrel of the ring terminal, and apply a crimping tool suitable for the terminal size to achieve a secure mechanical and electrical connection. Place the ring over the 3.2 mm screw or stud and tighten the fastener to the torque appropriate for the screw size and application. If soldering is preferred, crimp first to hold the conductor and then apply solder sparingly to avoid damaging the insulation. Ensure the insulation covers the barrel adequately and that no bare conductor is exposed beyond the lug.

Usage recommendations

Verify that the chosen cable cross-section matches the terminal’s intended conductor size and use the correct crimping die to ensure a reliable connection. Avoid overtightening the screw to prevent deformation of the ring or damage to the stud. For applications exposed to moisture or corrosive environments, consider additional sealing or selecting terminals with enhanced environmental protection.
