(10mm) M10 x 1.25 x 25 Fine Pitch Black 12.9 Grade High Tensile Hex Socket Cap Screws Self Colour Allen Bolts DIN 912-2 Screws

Product Information

The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. Zinc Flake coated high tensile steel class 12 - a higher tensile non-stainless grade for screws and bolts. Zinc Flake coated high tensile steel class 10 - a higher tensile non-stainless grade for screws and bolts. Identify the class by the embossed number on the head, then find the size of your bolt in the chart.

Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below.They have a proof load of 830 MPa, minimum yield strength of 940 MPa, and a minimum tensile strength of 1040 MPa. These thread sizes and classes represent bolts and screws, as well, as other standard external threads. that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident.

Size for size they are stronger than the coarse thread versions "in tension" as there is a larger stress (contact) area. At Machining Doctor, our mission is to serve the machining industry as a comprehensive and reliable source of technical information. ISO 965-1 Calculator, Formula and Table Length of engagement of mating threads is selected to utilize full tensile strength of a bolt prior to shearing and nut threads. Compare the bolts you have with the diagrams below, then refer to the appropriate chart to see the ideal tightening torque.We hope these metric bolt torque charts have helped you discover the correct tightening torque for the bolts you use. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. If you might need to look up the ideal tightening torque for metric class bolts again, why not bookmark this page so that you can refer to it more easily in the future?

Once you know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class). If you properly torque the bolts, they will provide the maximum amount of clamping force under load. We strive to be the go-to destination for professionals in the niche seeking information, knowledge, and expertise. They have a proof load of 970 MPa, minimum yield strength of 1100 MPa, and a minimum tensile strength of 1220 MPa. They are made of quenched and tempered medium carbon steel and can be plated with a variety of materials, most commonly zinc.Westfield Fasteners Limited is a company registered in England and Wales with company number 07215583. Some downsides of using Fine pitch bolts or screws are they are slower to install, so not ideal where quick fitment and removal are required and they are also more likely to suffer from thread galling (see our reference section).

Fine pitch bolts should be preferred if being used to adjust settings, as they give closer, more precise control. Depending on size, they have a proof load of 580-600 MPa, minimum yield strength of 640-660 MPa, and a minimum tensile strength of 800-830 MPa.
