Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". With MID Sleeves. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Great magnets and sturdy hooks
These are great hooks! I needed something quick and easy to move around - these fit the job perfectly. The magnets are strong enough to securely hold the ropes and cables I needed to hang, and yet we can move them around as needed. Great purchase!

works, just not the strongest magnet.
magnet will hold a drill but anything much heavier it will start to slide. have on e on fridge, 2 on safe and on on garage cabinet. fridge and safe hold the least, i guess due to plastic over magnet and coating on the safe and fridge. cabinet does best but still will slide with any significant weight. holds my drills ok however.
