Review on Master Magnetics Fastener Diameter RB45CX10 by Justin Hill

VERY strong magnets perfect for my application. Whenever I solder many items together, I use third hands and a vise. The problem is that everything slips. I attached these magnets to the PanaVice 201 base, third arms, clamp stands, and magnification stands. I then attached them to an 18" square metal plate I bought from a local steel supplier. anywhere on the record, and these magnets don't slide at all. They appear to be bolted on. The problem is solved.
