Screws & Bolts

It also excludes , which are covered under part 5. Part 1 does not specify properties for fasteners that have head geometries that reduce the of the fastener, such as and heads. With over 100 years of production history, the automotive industry has been at the forefront of manufacturing technology since its inception. Grade A bolts are the preferred style for most applications. The diameter and pitch combinations must adhere to and and the thread tolerances must adhere to parts 1, 2, and 4.

ASTM, SAE and ISO Grade Markings for Steel Fasteners

It defines mechanical properties for fasteners that range from M1. Therefore the same maximum diameters apply for 8. I have a small screw machine shop where I make spacers and bolts from 12l14 steel. A high quality of service represents a competitive advantage for civil engineers that can gain client fidelity and more, but this is becoming harder to accomplish with modern design expectations. The chemical composition is essentially restricted such that cold-heading grades of alloy steels 4037, 4140, 1541, etc.

ASTM F568M

Where material costs are an issue, Boron steels like 10B30 are increasing in usage Europe but be careful of the hardenability and heat treat practice. This document is only valid for Ovako material. The data and examples are only general recommendations and not a warranty or a guarantee. Nuts with specified proof load values — Coarse thread 5. Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread 2.

Grade 10.9 bolt

Nuts with specified proof load values — Fine pitch thread 7. Join your peers on the Internet's largest technical engineering professional community. The purchaser of an Ovako product has the responsibility to ascertain and control the applicability of the products before using them. With either of these two the heat treat concerns are minimized. Our experienced staff, which includes two Mechanical Engineers, is among the most knowledgeable in the industry. Fatigue performance and impact strength will be better with a cold headed part, so if this is a requirement for the application, beware. This Website is based in the United States and the information we collect is governed by U.

Some functions of the site may be lost. The standard was withdrawn in 2012. . We have the most extensive fastener inventory in the area. Set screws and similar threaded fasteners not under tensile stresses 6.

ISO 898 grade 10.9

You should have an honest conversation with your customer to decide whether or not machined parts should be used. General Information The steel grade variants are suitable for quenching and tempering to 8. Core hardness based on Rockwell scale. The standards define that the testing must be performed at , which is defined as between 10 and 35 °C 50 and 95 °F. If it must meet property class 10. The standards do not cover fasteners that would otherwise apply but require special properties, such as or.

Grade 10.9 bolt

Whether the transformative technology of the day was the assembly line, the integration of robotics into the manufacturing process, or the switch from steel to aluminum frame chasses, the automotive industry has consistently implemented advanced technology into its manufacturing and production workflow to improve manufacturing and product performance. Has greater tensile strength than Class 4. This standard is the origin for other standards that define properties for similar metric , such as and. It is titled: Standard Specification for Carbon and Alloy Steel Externally Threaded Metric Fasteners. By accessing or using the Website or otherwise providing information to us, you consent to the processing, transfer, and storage of information to the U. It is divided into five nonconsecutive parts: 1.

The limiting factor for maximum size is the amount of the martensite in the core of the material. Regards, Cory Please see for tips on how to make the best use of Eng-Tips Fora. Other material, covering the same international specifications, does not necessarily comply with the properties presented in this document. Tread carefully and follow the advice of the other posters. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm With exception to part 7, which defines test standards, the parts of this standard define properties for fasteners made of and.

ISO 898 grade 10.9

The suitability of a product for a specific application can be confirmed only by Ovako once given the actual conditions. The properties are defined for M1. Continuous development may necessitate changes in technical data without notice. This standard only applies to short screws and bolts with a nominal diameter between 3 and 10 mm. I have a customer who wants a 10mm bolt made which must be equivalant to a grade 10. These two additional standards are fasteners that have the same mechanical properties as their base property class i.
