An Overview of Decimal Point Shifting in Fasteners and Its Role in terms of Accuracy and Efficiency

April 13, 2021

If the fastener series is scaled upwards in size, then the engineer can convert the size in his head simply by moving the decimal point and thinking in centimetres. That is pretty much what decimal point shifting in fasteners is. Metric fasteners scale easily in size thanks to mathematical integers. That's to say, there are no messy fractions of an inch to deal with. Instead, manufacturers fabricate sets of bolts and label them in millimetres.

Decimal Point Shifting in Fasteners Ensure a Pitch-end to Perfection

Conventional imperial thread measurement tells us how many threads per inch exist on the body of a bolt rod. Conversely, metric fasteners use pitch distance in place of thread count, which represents a far more reliable method of defining the coarseness of a specified fastener. Thanks to this attribute, an engineer knows how fine or coarse the fastening mechanism is, which is an important feature. One that eliminates thread stripping while enhancing anti-vibration features.

The Need for Decimal Point Shifting Rose From Unrecognised Imperial Measurements

Regional errors plague imperial fasteners because of internationally shipped machinery. Thankfully, the metric system dominates the world stage, so there's a much greater likelihood that decimal point shifted fasteners will fit these imported machines. Conversely, imported machinery does not always favour the imperial system.

Decimal Point Shifting in Fasteners Creates Uniformity and Reliability

For most countries that still uses the English measurement system, they slowly recognize decimalized fasteners as a standard, one that's not going away, the changes will gather speed. Power-of-ten reliability will take over and neutralize thread counts while pitch distance becomes the accepted path. And, once pitch does dominate, then sharply defined threads that exactingly incorporate precision-imbued coarseness versus fineness characteristics will gain universal acceptance.

Decimal Point Shifting in Fasteners Promotes Consistency

Finally, the hardness and strength of the sourced alloys remain consistent across both measurement scales, so both products will work, but, and this is an important point, easy installation can only be guaranteed if matching bolts and nuts are purchased. Even then, intervenings holes may have been drilled by a metric drill bit, so always evaluate the measurement system in tandem with machinery screw holes and drilled holes, and keep every fastening element consistent.
