Hex Bolt 5.8

Hex Bolt 5.8

We like the weird ones! BelMetric stocks Class 5.8 Low-Strength rounded hex bolts in extremely rare sizes: M6X0.75 Fine, M8X0.75 Extra Fine and M12X1.0 Super Fine.


These bolt + nut sets can also serve as male / female thread gauges when determining the pitch of an unidentified thread pattern.


Please double check your thread pattern measurements prior to ordering these sizes.
