Product Overview
The Mueller BU-48B is a heavy duty steel spring clip with a non-insulated body and a 3-sided jaw. It carries a 10 A current rating, has zinc contact plating, and accepts either a crimp or screw lead connection - the slotted terminal screw is visible in the photos, along with the notched gripping nose and toothed jaw edges that let it bite flat stock or wrap a terminal from three sides. Each body is factory stamped MUELLER 48B 10 AMP, so the rating rides right on the clip. This is the classic automotive analyzer clip: the bare steel workhorse on the business end of countless shop test leads.

Frequently Asked Questions
How does the lead wire attach?
By crimp or screw connection. The slotted screw is installed on the clip, as shown in the photos.
Is this clip insulated?
No. It is a bare steel, non-insulated clip. If your work calls for an insulated clip, plan accordingly.
What is the current rating?
10 A. The rating is stamped right on the clip body: MUELLER 48B 10 AMP.
What is the M21046 number?
That is our stock number for this item. The manufacturer part number is Mueller BU-48B.
Why buy two or three clips here instead of a bulk bag on eBay or Amazon?
Because you probably need two or three, not fifty. We sell the exact quantity you want, shipping is a flat $8 and free over $28, and your order leaves our Idaho warehouse the same or next business day. For a couple of clips, that usually beats paying for a forced lot.
Every bench has a drawer where test clips go to get lost, and the steel ones are always the survivors. Crimp this one onto a lead and it will probably outlive the lead.
