Why LUBRICATE Stainless Steel fasteners?

You may ask yourself why should there be a need to apply lubrication to Stainless Steel Fasteners? After all they are Stainless, they should not need lubrication, they will not corrode. This section of the website attempts to explain why lubrication should be used to prevent two seperate possible issues, the possible results of not doing so and how this need has arisen. The intention is not to try and confuse or over complicate the issues, just attempt to […]

Which type of steel is used in bolts?

Stainless steel and low carbon steel hex bolts. Any steel with a high yield strength can be used, but series 4xxx low carbon steel and series 4xx tempered martensitic steel are widely used.

It depends where we are using that bolt
For rough and tough use hight tensile 10.8
For regular industrial general use c45 or En8
And lastly for general use where grading and performance is not the important factor, can use directly Mild steel

Mostly low carbon steel. There are different grades […]

How to deal with fastener burrs?

    Fastener burr refers to the very tiny microscopic metal particles on the surface of fasteners, the particles we have become burr.
How fastener glitches occur when fasteners are cut, ground, milled, and other similar chips are formed. In order to improve the serviceability and service life of fasteners, it is necessary to remove the fastener burrs before using the fasteners. Fasteners are the most commonly used parts on mechanical equipment, but also important parts, so the surface, acute […]

The Method of Calculating Tensile Strength of Hexagon Socket Head Bolts

Strength is the bearing capacity per unit area, is an indicator.
Formula: Bearing capacity = strength x area;
Threaded bolt, M24 bolt cross-sectional area is not the diameter of the circular area of 24, but 353 mm2, called the effective area.

Normal Bolt Grade C (grades 4.6 and 4.8) The tensile strength is 170 N / mm 2.
Then the carrying capacity is: 170×353 = 60010N. Conversion, 1 ton equivalent to 1000KG, equivalent to 10000N, then M24 bolts that can withstand about 6 […]
