・Cutting the right material with ultra-high precision
There are three types of materials: titanium, stainless steel, and aluminum.Each of these bolts and nuts is made of materials with the most suitable characteristics for fastening parts, and are subjected to ultra-precise machining and surface treatment with much stricter tolerance standards than ordinary bolts and nuts.
・carefully selected materials
No matter how beautiful the design and high-precision processing is, if the material is not good, it cannot satisfy the performance as a fastening part. Therefore, first of all, the material suitable for making all bolts, nuts, washers, etc. by machining was examined.As a result, we decided to use "TI6AL4V", which is called 64 titanium, and "A7075-T651" for aluminum.
・Ultra-high precision machining
Based on these materials, the tolerances are set for total machining, which allows precise dimensional control.This makes the "fit" against the mating part or the tool to be removed more secure.You will be able to feel the high accuracy of BOLZEN series by the smooth movement when you screw the bolt into the female thread while turning it with your finger, the small amount of rattle when you put the wrench on the head, and the increase of the axial force after the seat surface comes into contact.
・Surface treatment
Titanium and stainless steel, which are highly resistant to corrosion, are left with a machined surface (surface roughness at the level of general polishing), while aluminum is anodized to improve corrosion resistance and surface hardness.
・Design
The BOLZEN series is not only characterized by its materials and processing accuracy.The design is also unique and unparalleled.The flange hex bolts and banjo bolts have wirerunning holes and grooves on the heads for racing use.Two types of titanium flange hex bolts, one with a large diameter flange and the other with a small diameter flange, have been prepared for the purpose of function and usability.
The fact that our products have been delivered to several manufacturers as parts for their factory machines (MotoGP SBK AMA SX/MX WMX etc.) and are widely used in competition vehicles for road racing, motocross, trials, etc. is not only a sign of lightness and strength, but also a sign of the reliability of our products backed by our processing technology. It is also a sign of the reliability of our products backed by our processing technology.
This is the part for the rider who is as particular about one bolt, one nut and one washer as the machine itself.
