Quick Specs
What Buyers Should Know Before Sourcing Metric Stainless Steel Fasteners
Confirm Metric Standard and Thread Pitch
Metric stainless steel fasteners may follow DIN, ISO, EN, JIS, or drawing dimensions. Buyers should confirm diameter, pitch, length, head style, drive type, nut height, washer type, and tolerance before requesting production. XZ Fastener’s metric fastener size chart can help purchasing teams check common dimensions.
Select Stainless Grade by Environment
A2/304 stainless steel is widely used for general corrosion resistance, while A4/316 is commonly selected for marine, chemical, coastal, or more corrosive environments. The final choice should consider chloride exposure, temperature, mating material, appearance, and cleaning requirements.
Common Purchasing Descriptions
Metric stainless steel fastener inquiries should separate product type, standard, material grade, strength class, finish, and packing method. Clear wording helps avoid mixing stainless items with carbon steel items in the same project list.
- DIN 933 stainless steel full thread hex bolts, A2-70 or A4-70, plain finish
- Metric stainless steel hex nuts DIN 934, A2 or A4, coarse thread
- ISO 4762 stainless steel socket head cap screws, metric coarse or fine thread
- DIN 125 or ISO 7089 stainless steel flat washers packed with bolts and nuts
- Metric stainless steel machine screws with Phillips, hex socket, Torx, or slotted drive
- Related carbon steel orders may include DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts
For standards used across metric product families, buyers can review metric fastener standards, DIN, ISO, and EN explained.

Material and Grade Explanation
Stainless steel fasteners are selected when buyers need corrosion resistance, clean appearance, and stable performance in humid, outdoor, or chemical-exposed environments. A2/304 is commonly used for general industrial applications, while A4/316 provides improved resistance in chloride and marine conditions. For higher strength stainless bolts, A4-80 may be considered when the drawing or assembly requirement supports it.
For grade selection, XZ Fastener provides guides on 304 vs 316 stainless steel bolts and A2 vs A4 fasteners for corrosion resistance.
Surface Finish Selection Guide
Plain Stainless
Common for bolts, nuts, washers, and screws where natural stainless appearance is acceptable and no special surface treatment is required.
Passivated
Used to improve surface cleanliness and corrosion resistance after forming, machining, or handling. Passivation can be requested for suitable stainless grades.
Polished
Selected for visible assemblies, equipment covers, architectural details, and applications where surface appearance is important.
Waxed or Lubricated
Used to reduce galling risk during assembly, especially for stainless bolts and nuts in repeated installation or higher torque applications.
Blackened Stainless
Available upon request for selected products where a dark appearance is needed. The process and durability should be confirmed by application.
Special Surface Requirement
Electropolishing, cleaning, color marking, or customer-specific surface requirements can be discussed with drawings or samples.
For broader stainless selection, buyers can read stainless steel fastener benefits, applications, and grade selection.
Manufacturing and Quality Control
Metric stainless steel fastener production may include wire or bar material inspection, heading, turning, thread rolling, tapping, washing, passivation, polishing, sorting, inspection, and packing. Important checks include dimensions, thread fit, head style, drive depth, nut thread, washer inside diameter, material grade, surface condition, and label accuracy.
For inspection planning, XZ Fastener’s guide to fastener quality control during manufacturing explains practical checkpoints from raw material to packing.
