1.  What is Titanium Grade 5?

Known as the “workhorse” of the titanium alloys, Ti 6Al-4V, or Grade 5 titanium, is the most commonly used of all titanium alloys. It accounts for 50 percent of total titanium usage the world over.

Its usability lies in its many benefits. Ti 6Al-4V may be heat treated to increase its strength.  It can be used in welded construction at service temperatures of up to 600° F. This alloy offers its high strength at a light weight, useful formability and high corrosion resistance.

Ti 6AI-4V’s usability makes it the best alloy for use in several industries, like the aerospace, medical, marine and chemical processing industries. It can be used in the creation of such technical things as:

  • Engine components
  • Aircraft structural components
  • Aerospace fasteners
  • High-performance auto/moto/cycling parts
  • Marine applications
  • Sports equipment

2.  How is bolt length measured?

Bolt length is measured by the end of the thread to the bottom of the bolt head. The bolt head makes no difference in the measurement.  Example, a 20mm length hex head and socket head bolt will both have 20mm of thread and shank.  Only exception is countersunk bolt where the top surface of the head is included in the measurement.  Example, 10mm countersunk head bolt will be 10mm total length from end of thread to top surface of the head.


3.  How to determine correct diameter bolt?

Measure the hole diameter that bolt will be installed in. If the diameter is 5mm then you need a M5 bolt.  If 6mm then M6; 7mm is M7, 8mm is M8, etc.

4. What is thread pitch?

Thread pitch is the distance from the top of one thread to the top of the next thread. Example would be a M6-1.00 pitch thread. The distance would be 1mm from the top of one thread to the top of the next thread.

5. What does "shank" and "grip" length mean?

There are two terms that describe the smooth area between the head and threads on a bolt, “SHANK” and “GRIP”. Both terms are correct to describe the smooth area on a bolt. All shear loads should be positioned on the Shank/Grip area of a bolt. Shank/Grip length is measured from the start of smooth area under the head and ends where the threads start.

6. What is the difference between a machined thread and rolled thread? 

Machined treads are single point cut and tear the grains of the material to make thread. A rolled thread is formed by compressing the material with a rolling die. A rolled thread has higher strength and fatigue resistance. A rolled thread is much safer and this is why aircraft manufactures will only specify rolled threads on all fasteners.

7. What torque value should I use?

Use torque values specified by your equipment manufacture, when available. For titanium fasteners the torque values are listed below. We recommend anti-seize or moly paste be applied to the threads.

The importance of correct application cannot be overemphasized. Undertorque can result in unnecessary wear of nuts and bolts as well as the parts they hold together. When insufficient pressures are applied, uneven loads will be transmitted throughout the assembly which may result in excessive wear or premature failure due to fatigue. Overtorque can be equally damaging because of failure of the bolt or nut from overstressing the thread areas.
