Product Description
M6 Grade 8.8 Yellow Zinc Plated Steel Hexagon Head Bolts With Shank – DIN 931
M6 hexagon head bolts manufactured to DIN 931 from Grade 8.8 high tensile steel with a yellow zinc plated finish. These part-threaded bolts feature a plain shank beneath the head and an M6 × 1 metric coarse thread.
The hexagon head accepts a 10mm spanner or socket. Available in lengths from 30mm to 80mm for machinery, maintenance and general engineering assemblies requiring a bolt with an unthreaded shank.

Fitting Information
Use with matching M6 × 1 nuts or tapped holes. Select compatible nuts and washers of a suitable strength for the assembly.
Check that the bolt provides sufficient thread engagement and that the plain shank does not prevent the joint from tightening fully. Use a 10mm spanner or socket and follow the tightening requirements for the application.
