M6 x 9.8mm (D) x 10mm (L) Metric Coarse Zinc Cross Dowel Slotted JCB Barrel Nuts Low Tensile

About Cross Dowel Barrel Nuts

Cross Dowel Nuts are slotted cylindrical nuts used in knock-down furniture and joinery. The nut sits in a perpendicular hole in one workpiece while a bolt passes through the mating piece into the cross-thread, clamping the two together. The screwdriver slot on the end face lets you rotate the nut so the thread aligns with the incoming bolt.

Recommended use Indoor and dry-environment use only. Common in automotive, machinery and electrical assembly where the bolt is not exposed to weather, condensation or wet service.

Frequently Asked Questions

Material & Coating

Zinc Electroplated zinc on carbon steel. A thin (5 to 12 micron) bright (clear-passivated) zinc layer applied by electrolysis. Bright silvery finish.

Important NOT suitable for outdoor, wet, marine or treated-timber applications. The thin coating is consumed quickly by rainwater or treated-pine preservatives. For outdoor use, specify hot-dip galvanised.

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 1.00mm coarse pitch, meaning the peaks are 1.00mm apart.

How to Measure

Sizing Cross dowel nuts are sized by barrel diameter, barrel length and thread. The barrel diameter must match the hole drilled across the joint (a 10mm barrel needs a 10mm hole), the barrel should sit fully inside the timber, and the thread takes the connector bolt. The slot in the end lets you line up the thread hole with a screwdriver.
