Spade Connectors

Fork terminals for compatible screw connections

Spade connectors terminate wire with an open fork that fits a matching screw or barrier-terminal connection. Check the conductor gauge, screw size and space around the terminal before choosing a part. The screw-size number and AWG wire size describe different ends of the connector.

Compare standard and barrier spades

• Red vinyl, 22–18 AWG: RVST6 and RVST8 fit #6 and #8 screws respectively, with 100 terminals per pack.
• Blue vinyl, 16–14 AWG: BVST6, BVST8 and BVST10 offer #6, #8 and #10 sizes in 100-packs.
• Yellow vinyl, 12–10 AWG: YVST6, YVST8 and YVST10 offer #6, #8 and #10 sizes in 100-packs.
• Red vinyl, 8 AWG: RVST88 fits a #8 screw and comes in a 25-piece package.
• Barrier spades: US810 and US810-50 are for 8 AWG wire; US410 and US410-50 are for 4 AWG. All four use a #10 screw size and red/black identification sleeves. Install Bay describes their material or finish as nickel.

The base US810 and US410 packs contain five red/black pairs, or ten terminals total. Their -50 versions contain 25 pairs, or 50 terminals. Keep that pair-based packaging separate from the individual-piece counts used for the vinyl spades.

Spade connector questions

Are these the same as flat-blade quick disconnects?

These spades use a fork-shaped screw connection. For a male tab and female receptacle that plug together, choose the matching interface from Quick Disconnects instead.

Can I select by color alone?

Check the part number and gauge. Red appears on both 22–18 AWG standard spades and the 8 AWG RVST88; the barrier sets use red and black for identification.

Are all of these nylon insulated?

The standard spades specify vinyl. The US-series sleeve polymer is not specified in the manufacturer details. Consult the individual listing and equipment requirements before installation.
