Planning Guide

Plan the right fit before choosing

Electrical connection assortments

Select by connector style and wire range

Electrical maintenance kits include terminals, connectors, and wire nuts. Available terminal and connector styles include butt splices or connectors, male and female terminals, spade terminals, ring terminals, self-splicing connectors, quick connectors, closed quick splicers, and fully insulated slide terminals.

  • Compare wire ranges such as 22-18, 16-14, and 12-10, or 22-16 through 12-10 gauge, depending on the assortment.
  • Choose wire nut assortments when multiple wire-nut ranges are needed; one represented kit spans 18-16 AWG through 14-8 AWG.
  • Check connection sizes where listed: ring and spade options are represented from 6 through 1/4 inch.
  • Consider color-coded groups or compartmented storage when faster visual selection is useful.
Retaining clip and snap ring assortments

Match the shaft or rod requirement

E-clips and external snap rings are represented for retaining components including pulleys, sprockets, springs, and bearings on shafts and rods. The category includes carbon steel E-clips, steel metric E-clips, and a stainless steel metric external snap ring option.

  • Choose inch E-clips for listed sizes from 1/8 inch through 7/8 inch.
  • Choose metric E-clips or external snap rings when metric sizes are required; represented metric assortments include 16 sizes.
  • For external snap rings, one stainless steel assortment covers sizes from M8 through M45.
  • Use compartmented boxes to keep different clip sizes separated for selection and storage.
Grease fitting assortments

Check thread, drive, and access orientation

Grease fitting assortments provide straight and angled replacement options for lubrication-point service. Metric assortments include M6 x 1, M8 x 1, and M10 x 1 fittings, while another assortment includes 1/4-28 SAE-LT, 1/8-27 PTF, and M6 x 1 thread options.

  • Choose straight, 45-degree, or 90-degree fittings according to the required access orientation.
  • Select a drive-type assortment when 3/16 inch, 1/4 inch, or 5/16 inch fitting sizes are needed.
  • Compare all-in-one counts and contents: one metric set combines 95 grease fittings with 45 dome caps.
  • Some represented fittings include red dome caps, and one metric kit includes fittings with a spring-loaded ball that helps prevent dirt from entering the fitting.
