Frequently Asked Questions
What tool is needed to tighten the set screws?
A standard 1.5mm hex key tightens the dual set screws onto the stripped conductor wire. Tool not included.
What wire diameter fits inside the rear strain-relief boot?
The flexible boot and sleeve channel accommodate test wire with an outer insulation diameter up to 4.0mm.
Why buy individual banana jacks here instead of a bulk multi-pack?
Most industrial distributors require buying full contractor packs when you only need one or two connectors to rebuild a test lead set. Here you purchase the exact count required for your bench project without paying for excess inventory. If you are stocking up, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free at $28 and up, and leave our Idaho warehouse the same or next business day.
Nothing stops a troubleshooting session faster than an intermittent test lead. Fasten these set screws, snap the sleeve shut, and get your meter back on the line.
