The DIN 6922 standard published by the German Standardization Institute (DIN) describes the requirements for hexagonal flange bolts with small screed.
In the DIN 6922 standard, the requirements for small screed hexagonal flange bolts are listed under the following headings:
Similarly, in the EN 1665 standard, which is a European standard, The requirements are described for flanged hex bolts (heavy series) (EN 1665 Flanged hex bolts - Heavy series).
Hex flange bolts are regular hex head bolts with built-in washer and externally threaded shank. Flange bolts are manufactured with a flat or serrated flange configuration. Hex flange bolt sizes are defined in both metric and imperial sizes with a combined national coarse pitch, fine pitch, fixed pitch and isometric thread profile. These are manufactured in all material categories and specifications. Hex flange bolts are widely used in the automotive industry, especially in truck and heavy vehicle chassis. It is especially used in vehicle frames, truck frames and wherever a hex washer head bolt is required. The large bearing surface distributes the clamping force over a wide area, allowing them to be used with irregular and large-sized holes.
Hex flange bolts are often used in conjunction with Class G flange style locknuts to create a loosening resistant and widely spanned bolt/nut system. They are also known as hex frame flange bolts, hex washer frame bolts, hex flange screws. The serrated hex flange bolts have threads under their heads that engage the mating surface to resist loosening.
Our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, It also provides testing services for small screed hexagonal flange bolts within the scope of DIN 6922 standard and for flanged hexagonal bolts within the scope of EN 1665 standard.
