A brief cross-reference guide to some of the standards referred to on Technifast products Datasheets Material Specifications Pin Economics Plating & Finishing Recommended Hole Sizes Shear Strengths Standards Tolerances STANDARDS - ISO / BS / DIN DIN is the acronym for ‘Deutsches Institut für Normung’, which is the ‘German institute for standardisation’ who developed detailed technical standards for the engineering industry, amongst many other industries. With reference to fasteners, DIN number indicates the that the part conforms to a specific metric standard. The International Standards Organisation (ISO) standard has evolved to supersede the DIN standard, which was historically the predominant metric fastener system referred to. The intention of the ISO standard was to standardise the technical specifications worldwide to simplify the system and aid the flow of trade via a universally recognised standard. In practice, DIN and ISO standards are still both commonly used when specifying fasteners and both standards are recognised by Technifast when our customers specify the fasteners they require. The chart below shows the ISO standards and their equivalent DIN and BS standards.

Spacers are normally used to allow two parts of an assembly to be fastened together at a controlled distance from each other. We stock a wide range of mild steel, mild steel zinc-plated and stainless steel clearance spacers. The portfolio includes closed-seam rolled spacers, turned spacers - plus we also provide moulded spacers, which are available in nylon. Technifast’s threaded spacer and standoff ranges form integral components in a wide variety of assembly applications, spanning industries such as automotive, aviation and most commonly, electronic hardware. Threaded spacers and standoffs are frequently used to create a specified space between two objects and to properly position parts within an assembly. The threaded spacers and standoffs supplied by Technifast are available with a rounded or hex exterior, which allows for easy tightening by hand or with a wrench. The majority of our standard range is stocked in our warehouse facility, ensuring we can meet the demands of customers quickly and cost-effectively. Standard nominal thread sizes range from M4 through to M12 in the round threaded spacer, with outside diameters from 7mm to 15mm. The size range of standard hexagonal threaded spacers spans from M2 to M6 with outside diameters from 4mm to 10mm. Threaded spacers and standoffs are available in three configurations: male/female, female/female and male/male (made to customer specification). We also provide hexagonal studding connectors in thread sizes M5 to M36, threaded full length and PCB Spacers used in electronic circuit boards.

Recommened hole size guidance for Technifast products Datasheets Material Specifications Pin Economics Plating & Finishing Recommended Hole Sizes Shear Strengths Standards Tolerances RECOMMENDED HOLE SIZES It is important to follow the hole diameter instructions given by the various manufacturers and standards organisations, and the data given on our website and datasheets comes from these sources. However, the user should decide in the circumstances of a particular application which hole size, within the permitted tolerance range, to adopt as this can effect the performance of the pin considerably. The general principle is that the inserting pin or dowel requires significantly more force at the bottom of the hole tolerance range than at the top. This has the following implications;- The higher insertion force required, the more difficult the assembly operation, and risk of damaging or over-stressing the area of the material surrounding the hole is greater The harder the pin is to insert, the more firmly it will stay in place so in applications where vibration is a consideration, it may be worthwhile to use a minimum hole size. Where an interference fit is required (as opposed to a sliding or clearance fit) the dowel must be precision ground and the hole must be reamed. The relationship between the diameter of the pin and the diameter of the hole must take into account the ductility of the dowel and the hole material and will vary more accordingly to this factor than according to the size of the dowel itself. Visit our product pages or datasheets to access the required recommended hole size for each product. Should you require any further information, please do not hesitate to contact us on +44 1536 461140 or sales@technifast.co.uk .
