M20 x 40mm Hex Countersunk Screw ISO 10642 | A2-70 Stainless Steel
This ISO 10642 fastener uses an M20 thread combined with a 40mm length to suit equipment assemblies needing increased fastening depth. The 40.32mm head diameter allows the countersunk profile to sit neatly within prepared recesses on fabricated components.
Manufactured for engineering applications. The 10.16mm head height and H12 hex socket drive are specific to this variant, supporting controlled torque transfer. Unlike smaller or larger thread sizes, the M20 format is commonly specified for engineering and fabrication assemblies.
