304-A2 Stainless Steel Metric Lock Nut DIN 985 Stainless Steel

The 304-A2 stainless steel metric lock nut type DIN 985 is a fastener for stainless metric assemblies with moderate vibration, industrial maintenance and equipment exposed to moisture. At TECTUL it is specified by material, thread system and actual available size, because in industrial nuts compatibility depends on diameter as well as pitch and bearing type. For this product, the reference works with DIN 985, today related to ISO 10511 for thin prevailing-torque nuts with non-metallic insert. It differs from the stainless UNC lock nut because it uses metric thread, and from a DIN 934 hex nut because it incorporates a locking insert. It is a useful option for maintenance, manufacturing and replacement purchases when the correct part must be identified without mixing similar catalog families.

Installation recommendations

• Confirm diameter, pitch and thread system before forcing the assembly.
• Use a bolt or stud with material and strength compatible with the nut.
• Clean the thread and discard parts with dents, burrs or visible deformation.
• Apply the torque or procedure defined by equipment engineering, not by visual estimate.
