What to look for when buying plug sets

A high-quality assortment of ratchets, sockets and accessories is essential for many different jobs, from complex to light maintenance jobs. They come in several different sizes with wrench heads to match the individual size bolts. Here are some of the most important things to consider when buying plug sets:

Plug sizes

Different plug sizes are likely to include SAE, Metric, and Whitworth. The SAE (standard size plug) has its measurements in inches, which is practical for those mechanics working on older vehicle models. Metric tools are necessary to work on the latest domestic and imported vehicles with sizes in millimeters.

A garage must be stocked to match the type of vehicles being serviced. However, a combination of SAE and metric is the most practical option to ensure that a tool is available for the broader jobs.

The third type is the Whitworth plugs, which probably only appear on British vehicles like a classic Jaguar or MG.

Unit size

SAE and metric plugs are available in a variety of sizes, including ½ inch, 3/8 inch, and ¼ inch. The range of sizes is designed to work with the different ratchets and may even require an extension unit to function. For those who are limited to buying a single drive size, it is best to go for the 3/8-inch drive because it has the ability to work with most sockets.

The ¼-inch socket wrenches are the preferred choice for reaching bolts or nuts in tight spaces, while the large ½-inch socket wrench is practical for larger fasteners and has the ability to accept more torque. This type of plug may require a breaker bar or ratchet to fully tighten or loosen.

Points

The shape of the receptacles can vary from a 12 pointed star to a six pointed hexagon. The six point socket is the most reliable option because its walls are better able to sit flush with the sides of the nuts. They are most practical for applications that require significant torque or rely on large hardware. But the 12-point plug is the most convenient to use because it’s so much easier to fit and align, and a useful option for lighter jobs.

Steel alloy

The strength and durability of plugs can vary significantly. One of the most durable options is alloy steel that is hot forged from various other materials. It is essential to have a reliable material that has the ability to provide long-term service and will withstand the toughest jobs.
