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 […]
