The Sealey BT24 Easy-Entry Ring Terminal is designed for professional electricians and dedicated DIY enthusiasts who require secure, high-quality electrical terminations for 16-14 AWG wire. These terminals offer a reliable connection for grounding or power distribution projects, though they are specifically sized for 4.3mm studs and may not be suitable for larger bolt diameters without modification or alternative parts. This pack provides 100 color-coded units, ensuring consistent performance and organization for large-scale wiring installations.

The BT24 is designed for use with 16-14 AWG wire.
This terminal has a ring hole diameter of 4.3mm (4BA).
Each pack contains 100 ring terminals.
No, these are standard insulated crimp terminals; they do not shrink when heated.
Use a standard insulated terminal crimping tool capable of handling the blue (16-14 AWG) category.
Verify that the crimp tool is set to the correct wire gauge setting and that the wire was stripped to the proper length before insertion.
The 4.3mm ring size is fixed; if the mounting bolt is larger than 4.3mm, use a larger ring terminal rather than drilling out the existing one, as this weakens the terminal.
Check that the terminal has been crimped fully and that no insulation is trapped between the crimp and the wire strands.
To achieve the best results with the Sealey BT24, ensure the copper wire is stripped to the appropriate length—typically 5-7mm—so that the wire strands sit firmly within the barrel without extending too far past the contact area. Always match the terminal with the correct gauge wire; attempting to use a smaller wire will result in a weak, high-resistance connection, while a larger wire will not fit the barrel. For maintenance, keep the remaining terminals in their original packaging to protect the copper from moisture and oxidation. If the connection point is exposed to the elements, consider applying a thin layer of dielectric grease or using heat shrink tubing over the crimp area to prevent corrosion.
