Metric Fasteners Keep the Medical Industry Running

medcartOver time, metric fasteners can wear out, work loose, or break off. The more a piece of equipment is used, the more often metric fasteners will need to be replaced. With a 24/7 schedule, few industries are as hard on equipment as the medical industry. Everything from handcarts to ultrasounds are used and relied on constantly within the medical industry by rotating shifts of employees.

This puts a lot of strain on medical equipment, and makes repairs a frequent problem. Finding the right metric fasteners is key to getting medical equipment up and running again.

Metric Fastener Markings: What Do They Mean?

Most people would be amazed by the amount of information that can fit on the head of a bolt. As you may already know, information about the diameter, length, and thread pitch of a fastener can often be found on its head. However, there’s a lot of other information that manufacturers put on the head of a bolt that you may not know about. That information can make a big difference in the type of bolt you choose for your application. Here, we’ll look at some of the markings, and what they mean in terms of real-world applications

Benefits of Using Metric Fasteners Over Imperial

The debate over whether to use imperial or metric fasteners has been going on for well over a century. During that time, metric has consistently won out over imperial, even in the country that was responsible for creating the imperial system.

To understand why metric is the preferred system worldwide, it’s important to understand how each system works.

Different Drives for Different Metric Screws

Metric Fasteners with Different Drives

Does the sheer variety of screw drive types, from flat-head to Phillips and everything in between, drive you crazy when it’s time to buy? The “drive” is the combination of tool and screw-head pattern that allows the screw to turn — but unless you know why these different drives exist and what each type brings to the table, you might as well just guess blindly as to what you need and why you need it. Let’s examine why all these metric drives exist and how they function.

DIN and Standards for Fasteners

DIN and Standards for FastenersMost of the world has gone metric in its industrial measurement standards, which is why Mr. Metric enjoys such a booming business as the premier supplier of metric fasteners in the U.S. But since we don’t necessarily “think metric” on this side of the planet, it’s understandable that you might be puzzled by the various international standards sporting esoteric acronyms such as DIN and JIS. Allow us to shed a little light on the subject so that you can order your metric fasteners with confidence.

Nylon Patching for Fasteners

Nylon Patching for FastenersIf the metric fasteners we sold at Mr. Metric always made their home in stationary applications or objects, we might never have to worry about them losing their grip over time. Unfortunately the real world doesn’t stand still, and even the highest-quality screws in the world can come loose if the components it joins are subjects to constant vibration. Engines, motors and the parts attached to them vibrate pretty much whenever they’re in use. What’s the solution? Nylon-patched screws.

Applying The Right Torque

Metric Fasteners and Torque

Proper Torque

Applying the right torque to a fastener is something of a balancing act. Add too little torque and your fastener becomes a “non-fastener “– it simply slides back out of the hole. Add too much torque, however, and the force may be more than the screw can bear, causing stripped threads or even outright breakage. The materials that make up the fastener will have some say in how much torque you can safely apply. Nylon and softer metals will enjoy less torque tolerance than, say, stainless steel. Automated assembly lines for specific applications have to be told how much torque to apply. Once the ideal amount of torque is known for a particular assembly or sub-assembly, the machines that drive the fasteners into place can then deliver that precise amount every time.

Metric Fasteners for Bicycles: Let the Part Fit the Usage

metrics fasteners for bikes

If you know anything about cycling at all, you know that weight affects speed in a big way.

That’s why so many bicycle hobbyist are obsessed with finding the lightest parts and components possible for their bikes, right down to the metric fasteners holding the thing together.

Light frame tubing metals such as aluminum, magnesium and especially titanium may dazzle you with the promise of minimal density. So it seems sensible enough to use metric fasteners made of super-lightweight materials as well — that is, until your bike falls apart.

The Right Fastener For The Job


One fastener does not fit all. Do you have the right ones for your needs?

Many of the screws we sell work for a wide range of applications. Examples of good general-purpose fasteners include our line of metric pan screws, which come in slotted, Philips or Torx varieties. If you don’t have, say, a truss, or binding head screw, you can most likely drop one of these in as a substitute. Other screws, however, work well in one type of situation but not in another.
