Description of Stanley Proto J7214PF Strength Magnetic
ProtoGrip Magnetic Sockets use high-strength magnets made from a rare earth magnet alloy/nylon blend. ProtoGrip Magnetic Sockets require no bushings to hold the magnet in place. Designed to easily pick up heavy fasteners and hold them tightly during use. Strong magnetic hold helps increase efficiency when installing fasteners in awkward or hard-to-reach locations. Power sockets with high surface hardness are used in high-speed assembly operations. Ideal for nut runners.
As an automotive technician, I rely heavily on my tools every day. As a result of using this magnetic tool, I found that it securely holds screws and bolts in place, making it easier to access and manipulate hard-to-reach places... The strength and durability of this tool are unmatched and it has quickly become a staple in my toolbox. My only small complaint is that it can be a bit bulky, but the benefits far outweigh this minor issue..
Pros
Strong magnetic grip for secure holding of fasteners.
Cons
May lose its magnetism over time with frequent use.
works very well but the magnet is getting weak I need a stronger magnet to hold my engineering screws very important when trying to hurry up and do the work to do on time
