Stainless Steel Lag Screws Manufacturer in India with Exceptional sizes, standard, and Quality

Although stainless steel alloys tend to have high strength and superior resistance to corrosion, it is possible to increase these properties by use of surface treatment. For instance, the Lag Bolts manufacturer in India could galvanize them in order to improve their toughness as well as their resistance to corrosion. The main difference between any type of galvanized vs stainless steel lag bolts is that the former has a coating of zinc layered on its surface.

In comparison to electroplating, bolts that are galvanized have a higher degree of protection because the 3/8 stainless steel lag bolts that have been processed by galvanization receive a much thicker coat of finish as opposed to a thinner coat in electroplating. Moreover, the zinc coat applied to these components improves not only its hardness but also improves the stainless steel lag bolt strength, while coating the fastener to prevent contact with corrosive media. Galvanizing the material has an advantage that the component, or in this case the 1/2 x 6 stainless steel 316 lag eye screw will not get easily corroded, especially by oxidation, which is the most common cause of corrosion.

However, the rate of oxidation could be further brought down by the use of an alloy grade to produce a 1/2 x 6 stainless steel lag eye bolt that has a significantly higher content of chromium. One such alloy is grade 316, which has a content of 16.5% chromium its total alloy weight. The chromium content of more than 14% in stainless steel lag eye bolt with ring can form a thick passivate oxide layer which protects the fasteners from oxidation corrosion.

lag bolts vs lag screws

There is no distinction between lag bolts and lag screws. Both are called lag screws. Longer screws or bolts have space between the head and the threads that are known as a shoulder. Bolts are a kind of affixing with threads that can be utilized with a nut.
