METRIC HEAD MARKINGS

Many metric automotive bolts are stamped with numbers creating a lot of confusion as to the actual grade (hardness) of the bolt. We see bolts with a 9, or a 7, perhaps even a 10 stamped in the head.  These numbers do not give us any insight as to the size or hardness of the bolt. The other common mistake people make is to size their bolt based upon the wrench size. This also leads to misunderstanding the size and hardness of the bolt in question. The three most common Metric Head Markings (hardness) are:

  • 8.8     Equivalent to our American Grade 5 hardness.  PSI tensile strength of 120,000.
  • 10.9   Equivalent to our American Grade 8 hardness.  PSI tensile strength of 150,000.
  • 12.9   Equivalent to our American Allen Head bolts.  PSI tensile strength of 180,000.

How to ruin your Drill Bit in 2 easy steps! – Pro Tip of the Month

HOW YOU CAN RUIN YOUR DRILL BIT IN 2 EASY STEPS

Ruining a drill bit is one of the easiest things to do and we see this all the time!  Too much speed and too much pressure are the number one enemies of any cutting tool. We sell very high quality domestic cutting and drilling bits of all kinds; lettered bits, numbered bits, fractional bits, cobalt bits and also carbide burrs. Let me say it again-regardless of the quality, too much speed and too much pressure will ruin the best of bits.

One of the best things you can do is get in the habit of using a drop or two of a good cutting oil. We sell MEGACUT threading and cutting Fluid in 1 ounce and 4 ounce bottles and it is also available by the gallon by special order. This is an excellent cutting oil. (meets military spec. MIL-STD-767). Also let me note that using WD40 is the WORST thing you can use as a cutting fluid. It does NOT cool … it evaporates and can actually trigger heat and friction. So, save the WD40 for another project. Get yourself some MEGACUT, ease up on the speed and the pressure and you’ll get much better results as well as a longer life span for the drill bit !!!

San Carlos Mexico Scuba Trip!

One of Mark’s favorite Saturday adventures is a trip to San Carlos, Mexico. Adjacent to the big Mexican port of Guaymas, the small town of San Carlos is home to many American retirees and a great destination for deep sea fisherman and scuba divers! We have had many fun trips with fellow divers to this little town. Our favorite dive site is a little island about 20 miles offshore. Not only is there beautiful and abundant marine life but there is a sea lion colony that enjoys interacting with the divers. If only San Carlos wasn’t an 8 hour drive from home…..
