![]() ![]() For conversions from inches to millimeters: multiply the number by 25.4.For conversions from millimeters to inches: multiply the number by.If you’re interested in doing bit conversions yourself, all you’ll need is a calculator and these formulas: Or, if you prefer to avoid doing math altogether, a pocket bit gauge is worth its weight in gold. ![]() If you’re a regular Einstein, you can do the math yourself. So, what do you do when you need to make conversions from standard to metric? There are two different ways to tackle this issue. You’re regularly going to encounter fasteners or hole sizes that are sized metrically, usually in millimeters. Just because your drill bits are sized in fractions doesn’t mean the rest of the world is. So far, everything has been relatively straightforward and easy to understand. Most standard screws are sized by number, from 1-12, and each of those numbers corresponds to a different drill bit size. Matching Bits to Screwsįor new construction, it’s essential to know which drill bit corresponds to which screw size. However, if you have bits in these sizes, you’re well on your way to having every drill bit you’ll ever need. Keep in mind that there are hundreds of more bits beyond the ones that we’ve covered here. Here are the most common sizes for a standard (fractional) bit set: 1/16 ![]() As a rule of thumb, any set that contains 20 or more bits should be more than enough for most craftsmen. Of course, some bits have specialized applications and aren’t relevant for most basic work around the house.Ī typical set of drill bits includes somewhere between 12 and 30 bits. Maybe a better question would be how much time you have!Īll kidding aside, when it comes to drill bits, there’s a seemingly endless array of different sizes. Today, we’ll cover a drill bit size chart, so you can ensure you always have the right tool for the job. Considering the sheer volume of different bits on the market, this is easier said than done, and it gets even more complicated once you realize that not all measurements correspond to standard bit sizes. Having the right drill bits on hand is critical, whether you’re a weekend warrior, or a professional carpenter or contractor.

Intended for some pressure-treated wood sill plate applications. Mechanical galvanizing meets ASTM B695, Class 65, Type 1. Titen HD® Anchor Product Data - Mechanically Galvanized using a torque wrench, driver drill or cordless 1/4" impact driver with a maximum permitted torque rating of 100 ft. * These models do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. Titen HD® Anchor Product Data - Zinc Plated Length of anchor is measured from underside of head to end of anchor. Models THD37134H and THD37212H do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. Larger holes are not required for wood or thinner cold-formed steel members. Suggested fixture hole sizes are for structural steel thicker than 12 gauge only. Tighten the anchor into the base material until the hex-washer head contacts the fixture.Insert the anchor through the fixture and into the hole.(Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping. ![]() Drill the hole to the specified embedment depth plus minimum hole depth overdrill (see table below) to allow the thread tapping dust to settle, and blow it clean using compressed air. Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. ![]()
