Unbrako bolts are known to be manufactured from good quality stainless steel grades. these allen bolt fasteners are considered safe along with being the produced by the latest innovative technique. The Unbrako fasteners are available in the market in stainless steel grades such as grade 304 and grade 316. Unbrako fasteners are certified with the AD 2000 Merkblatt WO. Apart from having a higher tensile strength, these fasteners also display excellent resistance to corrosion in comparison to other hex or allen bolts. A point to note is that the properties exhibited by the fasteners such as hex or allen bolts, are dependent on the stainless steel grade they are manufactured in or ordered in by the buyer. Check out the unbrako hex bolt price list 2018.
The Unbrako stainless steel grade fasteners available in the market across a wide range or broad spectrum of size ranges or dimensions. For example, they are available in the following - screws and nuts, hex head threaded rod, socket head screws, washers (plain & spring), and socket set screws. See the unbrako hex bolt price list, available in the following dimensions - A2-70, A2-80, A4-70, A4-80, A4-90 and A4-100.
Many companies that manufacture the unbrako allen bolt, offer Specialized surface treated fasteners on the basis of end use or as required by the buyer. For instance, a wide range of surface treatment or coating on the unbrako allen or hex bolt is done in-house. Surface treatments include processes like Galvanizing which could be done by either Hot Dip or Mechanical Galvanizing, Zinc or Zinc- Nickel electroplating. Similar to coating with zinc, Unbrako fasteners are surface treated to other in house coating processes using chemicals such as Delta Dorken® , PTFE coating, Geomet® and Unbrako Wiscoat etc. learn more about coated unbrako allen bolt price list 2017.
In comparison to standard fastener grades, the tensile specifications for Unbrako fasteners are 10,000 psi higher. unbrako hex bolts generally have a higher tensile strength as opposed to industry standard. unbrako allen or hex bolt also tend to maintain their core hardness range.
Features of the Unbrako fasteners include -
E-CODE™ Head Marking is known as a fastener tracing method. The marking on the head includes details like raw material chemistry, original manufacturing lot, and performance test results to list a few details.

This design change in the Unbrako fasteners with regards to the Compound Fillet Radius, alone is responsible for doubling fatigue life at critical head-shank stage. Further the 3R or Radiused Root Runout, delivers a smooth form, which not only aids in the distribution of stress in the unbrako bolts but also increases fatigue life of thread run-out to as much as 300% in some sizes. See more details about the unbrako allen bolt price list 2019 here.
The Etching on Thread Laps is a method used to detect thread laps, where random samples of rolled threads are etched in a heated acidic solution. This is then followed by examining the threads under a stereo microscope. Rolled Threads of the Unbrako bolts are known to compresses the material’s grain flow and thereby, enhancing fatigue resistance.Continuous Forged Heads and flow lines result in an increase in mechanical properties of the unbrako bolts like tensile strength, better installation ability and a longer product service life.
