M16 x 2.00p Metric Coarse Galvanised K0 Structural High Tensile HSFG Bolt / Nut / Washer AS1252:2016

About K0 Structural Bolts & Nuts

K0 Structural Bolts are high-strength friction-grip (HSFG) bolt assemblies supplied as a matched bolt, nut and washer set certified to AS1252:2016. K-class assemblies are designed to be tightened to a specified minimum shank tension so the joint relies on friction between clamped plates rather than on bolt shear. The K0 specification covers galvanised assemblies for general structural steel use, including connections in building frames, bridges, transmission towers and crane structures.

Frequently Asked Questions

Material & Coating

Galvanised Hot-dip galvanised carbon steel. The standard outdoor finish; thick zinc coating gives decades of corrosion resistance. The right choice for trailer chassis, mast and pole mounting, structural pipe clamping and outdoor tank fittings.

Matching Finishes Always match the finish across the assembly. Hot-dip galvanising adds a much thicker coating than zinc plating, so a zinc-plated nut will not wind onto a galvanised bolt, and a galvanised nut on a zinc-plated bolt will be loose. Pair galvanised bolts with galvanised nuts and washers.

Important Performance in permanent coastal applications (within 300 metres of the sea) is reduced. Refer to AGA technical bulletins or contact us for the right grade for severe marine exposure.

Class Metric fasteners are classified as class 2, 4.6, 8.8, 10.9, 12.9, 14.9. See the head marking chart and full strength table.

Thread Pitch & Terminology

Thread Pitch (Metric) Metric fasteners measure thread pitch as the distance between thread peaks, expressed in millimetres. Metric also branches into three series: coarse (the default; widest tolerance, easiest to tap), fine (a tighter pitch for higher clamp load or thinner walls), and extra fine (the tightest pitch, used for thin-wall tube, precision instruments, and aerospace fittings where vibration loosening must be minimised). Always match the series as well as the size - a metric fine nut will not engage a metric coarse bolt of the same diameter, and an extra fine nut will not engage either. This product has a 2.00mm coarse pitch, meaning the peaks are 2.00mm apart.

How to Measure

Fastener Length This product has a head that sits on top of the material, so the length is measured from directly under the head to the tip of the thread. The head itself is not included in the size.

Thread Length On a bolt the thread length runs from the start of the unthreaded section (called the shank) to the end of the thread. To view the thread length for this product, select a length above.
