<\/figure>\n\n\n\nDo titanium bolts break?<\/h3>\n\n\n\n
If you ask, \u201cDo they break?\u201d the answer is: \u201cYes, they do.\u201d<\/p>\n\n\n\n
However, what this really means is: \u201cIf you intentionally try to break them, they can be broken.\u201d
Any material will fail if loads beyond its strength limits are applied.<\/p>\n\n\n\n
And this is not unique to titanium.
Steel and stainless steel bolts behave the same way.<\/p>\n\n\n\n
In fact, titanium bolts are often stronger than steel or stainless ones.<\/p>\n\n\n\n
So why did people used to say \u201ctitanium breaks easily\u201d?<\/p>\n\n\n\n
There are strong titanium bolts and weak titanium bolts.<\/h3>\n\n\n\n
Simply saying \u201ctitanium\u201d actually refers to various types.
Among them, the two commonly used for bolts are:<\/p>\n\n\n\n
Ti-6Al-4V (Grade 5) In the motorcycle industry, when people say \u201ctitanium bolts,\u201d they are usually referring to Ti-6Al-4V (Grade 5). Of course, our (Moto Rockman) bolts are also made from Ti-6Al-4V. As for the other type, commercially pure titanium (Grade 2)\u2026 Yes\u2014those \u201ctitanium bolts that break\u201d are actually bolts made from commercially pure titanium.<\/p>\n\n\n\n The term \u201cpure titanium\u201d may sound premium, but in reality it\u2019s the opposite. Ti-6Al-4V is an alloy consisting of titanium with 6% aluminum and 4% vanadium. The \u201ctitanium bolts that break\u201d were actually commercially pure titanium bolts, and the reason this idea became widespread was a long-established bicycle parts manufacturer.<\/p>\n\n\n The bolts included with the stem sold by this company were made of commercially pure titanium. I\u2019m not sure whether titanium bolts were a selling point of the product or not. From here, I will explain how to avoid mistakenly buying commercially pure titanium and how to distinguish it. \u30fb Check the labeling Machining marks: First, check the product tags or labels. \u30fbGrade2 \u30fbGrade5 \u30fbTi-6Al-4V If a product is significantly cheaper than the market price, it is suspicious. Companies in the industry, including ours, set list prices with wholesale distribution in mind. Products sold through those kinds of B-to-C channels are often cheaper. By the way, bolts sold at home improvement stores and construction supply shops are all commercially pure titanium.<\/p>\n\n\n\n Next is how to identify it visually. Bolts that remain in a forged state like this, without machining marks, are commercially pure titanium. The tricky one is this: If the edges are rounded like this and have no sharp corners, it is not machining but polishing. In addition, there are anodized commercially pure titanium bolts as well. There are also machined stainless steel bolts. <\/p>\n","protected":false},"author":1,"featured_media":15692,"template":"","class_list":["post-15678","tips","type-tips","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/tips\/15678","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/tips"}],"about":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/types\/tips"}],"author":[{"embeddable":true,"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/users\/1"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/media\/15692"}],"wp:attachment":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/media?parent=15678"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
<\/strong>Commercially pure titanium (Grade 2)<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n
In Japan, this is commonly known as \u201c64 titanium.\u201d<\/p>\n\n\n\n
To be clear, this is a very strong material.<\/p>\n\n\n\n
its strength is less than half that of 64 titanium (Ti-6Al-4V).<\/p>\n\n\n\nCommercially pure titanium bolts (Grade2)<\/h3>\n\n\n

In both titanium and aluminum, materials labeled as \u201cpure\u201d are generally weaker.<\/p>\n\n\n\n
As such, in general, alloys are stronger than pure metals.<\/p>\n\n\n\nWhy the idea that \u201ctitanium breaks easily\u201d became widespread<\/h3>\n\n\n\n

From what I\u2019ve heard, they tended to break quite often.<\/p>\n\n\n\n
However, it appears that this incident helped spread the rumor that \u201ctitanium breaks easily.\u201d<\/p>\n\n\n\nHow to identify commercially pure titanium bolts<\/h3>\n\n\n\n
There are four ways to identify it.<\/p>\n\n\n\n
\u30fb Check the price
\u30fb No signs of machining (cutting)
\u30fb Polished edges<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n1. Check the labeling<\/h4>\n\n\n\n
There are several terms used to indicate pure titanium and 64 titanium.<\/p>\n\n\n\n
\u30fbGr2<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
\u30fbGr5<\/p>\n<\/div>\n\n\n\n
\u30fbTAB6400<\/p>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n2. Check the price<\/h4>\n\n\n\n
However, there are also cases where 64 titanium is sold at extremely low prices.<\/p>\n\n\n\n
However, today it is possible for individuals to import products directly from overseas and sell them.<\/p>\n\n\n\n
If they are truly 64 titanium, there is no problem.<\/p>\n\n\n\n3. No signs of machining (cutting)<\/h4>\n\n\n\n
This is a commercially pure titanium bolt.<\/p>\n\n\n![\"\"](\"https:\/\/tsrjp.com\/wp-content\/uploads\/2026\/03\/06-img.webp\")
<\/figure>\n<\/div>\n\n\n
With low-cost pure titanium bolts, there is no reason to perform additional cutting or machining.<\/p>\n\n\n\n4. Polished edges<\/h4>\n\n\n\n
barrel-polished bolts with a glossy finish.
It can easily be mistaken for a machined bolt.<\/p>\n\n\n![\"\"](\"https:\/\/tsrjp.com\/wp-content\/uploads\/2026\/03\/07-img.webp\")
<\/figure>\n<\/div>\n\n\n
If you have never seen genuine titanium bolts before, you might mistake them\u2014so be careful!<\/p>\n\n\n\n
For those, you should also check whether they have actually been machined.<\/p>\n\n\n\n
These cannot really be identified without physically handling them.
At that point, it is essentially fraudulent.
