Choose the actual head and thread for the fastener enquiry. The photograph shows elongated transverse-head bolts with hexagonal nuts rather than a verified square-flat-head configuration.
Dimension the head bearing and anti-rotation contact
State head width, contact geometry, under-head length, diameter and pitch. Select one metric or inch thread standard and define mating-nut engagement for the intended joint.
- Select square or transverse head on the drawing.
- Specify actual stainless material and property class.
- Define thread, shank and bearing dimensions.
- Confirm nut inclusion and compatible passivation.
- Agree dimensional and relevant mechanical inspection.
Keep material grade separate from fastener class
A2-70 and SS304 are different specification references. SS316, carbon steel and high-strength steel are alternatives; the general class menu does not certify the pictured fastener.
Confirm evidence for the supplied joint
YS001 is a source identifier. Tightening, load capacity and corrosion life require applicable material and fastener records for the selected configuration.
