DIN 933 dimensions chart is a reliable and precise metric dimensions chart of fully threaded hex bolts from M2 to M64. When selecting fasteners for engineering drawings, bills of material and procurement, it is essential to have accurate dimensional information for width across flats, head height, thread pitch and nominal weight. The two specifications DIN...

Jade Alloys is frequently asked to explain the difference between two of the most widely used nickel alloy families in industrial supply, Monel and Inconel. Both are built around a nickel base, and both carry a reputation for handling corrosive and demanding environments other metals cannot, yet the two behave quite differently once you look at what...

Jade Alloys is regularly asked for a heavy hex nut weight chart by buyers preparing a bill of quantities or working out freight costs for an order of stud bolts and nuts. A heavy hex nut is not the same part as the standard hex nut covered on our hex nut weight chart. It is wider across the flats...

Jade Alloys manufactures both ASTM A193 B7 bolts and ASTM A193 B16 bolts, and the question we hear most often from buyers choosing between the two is not about strength, since the two grades are extremely close on paper, but about temperature. The real difference between B7 and B16 shows up only once a joint...

Engineers and purchasing department staff frequently seek assistance from Jade Alloys when it comes to explaining the similarities and differences between the two most popular superalloys, Inconel and Hastelloy. Although both families comprise nickel-based alloys, their actual behavior in real-world conditions may differ. The most important aspect is the differences in the composition. Inconel, which...

The procurement manager, structural estimator, freight coordinator, or anyone who must prepare bill of quantities and calculate shipping needs using accurate figures should have a satisfying and accurate hex bolt weight chart. Most of the reference charts published, however, combine partial-thread hex bolts and fully threaded hex screws into a single unlabeled reference chart without...

Choosing between A2-70 stainless steel bolts and Grade 8.8 carbon steel bolts is one of the most common fastener specification questions we field. Both are workhorse grades, but they solve different problems. At Jade Alloys, we manufacture and stock both, so this comparison is written from the position of someone who has to get the...

Jade Alloys is a leading manufacturer and exporter of industrial fasteners, serving piping engineers and procurement teams sourcing flange bolting for refineries, offshore platforms and process plant worldwide. Most flange stud bolt questions come down to the same three things. How many studs, what diameter, and how long. Get any of them wrong and you...

Jade Alloys is a leading manufacturer and exporter of industrial fasteners, serving piping designers, procurement teams and field inspectors across refineries, offshore platforms and process plants worldwide. Getting stud bolt sizing right on flanged joints, valves and pressure piping comes down to two things. Keeping the plant safe and not paying for a leak later....
