Fasteners & hardware
Part of the Metallurgy & Metalworking sector
Fasteners and hardware are the standardised metal parts that hold assemblies together — bolts, nuts, screws, washers, rivets, anchors and related fittings. This hub explains the main types and how to find and compare verified suppliers on Digibition.

Overview
Fasteners are mechanical parts that join or secure components: threaded bolts, screws, studs and nuts, along with washers, rivets, pins, anchors, clips and specialty fasteners. General hardware extends to hinges, brackets, handles, latches and fittings used across construction, machinery, furniture and vehicles.
Most fasteners are standard parts defined by a published standard, a dimension and thread, a property class or grade (which fixes strength), a material such as carbon or stainless steel, and a coating such as zinc plating or hot-dip galvanising. Because they are produced in very high volume, they are usually sourced by specification and quantity rather than to a custom drawing — though special and made-to-print fasteners also exist.
Buyers here include manufacturers, assemblers, construction and MRO operations, and distributors. On Digibition, fastener and hardware manufacturers and distributors publish verified profiles so professional buyers can discover and compare them by specialization and country.
What to check when sourcing
When you source fasteners and hardware, the specification comes first: the standard, the dimension and thread, the property class or grade that fixes strength, the material and the coating. Matching all of these — not just a similar description — ensures the part fits and performs as intended.
Beyond the specification, weigh the minimum order quantity and packaging, lead times and stock availability for standard lines, and whether a material or test certificate (such as EN 10204 3.1, given here only as an illustration) is provided where the application needs documented strength or traceability. For critical or structural fastening, confirm the marks and documentation your market requires.
Use the directory to shortlist suppliers by specialization and country, then contact several and compare specification, certificates and lead times before you commit.
What to check when sourcing fasteners & hardware
| Criterion | What to look for |
|---|---|
| Standard & type | The published standard and fastener type, not just a description |
| Dimension & thread | Diameter, length and thread pitch matching your assembly |
| Class / grade | The property class or grade that fixes strength for the application |
| Material & coating | Carbon or stainless steel and the coating, e.g. zinc or hot-dip galvanised |
| Certificate | Material or test certificate (e.g. EN 10204 3.1) where strength matters |
| MOQ & stock | Minimum order quantity, packaging and availability for your volume |
Frequently asked questions
- What does a fastener property class mean?
- A property class or grade marked on a bolt or nut defines its mechanical strength — for example its tensile strength and yield. Matching the class to the application is essential, because an under-rated fastener can fail under load. The required class is set by the joint design.
- Which coating should I choose for fasteners?
- Coatings protect fasteners from corrosion: zinc plating suits general indoor use, hot-dip galvanising gives heavier outdoor protection, and stainless steel resists corrosion through the material itself. The right choice depends on the environment, strength and any appearance requirement.
- Can I order special or made-to-print fasteners?
- Yes — alongside standard catalogue parts, many suppliers produce special fasteners to a drawing, with non-standard dimensions, threads or materials. Share the drawing, quantity and any certificate requirement so suppliers can confirm feasibility and quote.
- How do I find fastener and hardware suppliers?
- Use the Digibition directory to filter by this specialization and by country, then open each company profile to review its products, certifications and specializations. You can message suppliers directly, or add several to a quote list and request quotes from all of them at once.
- What should I check before placing a large order?
- Confirm the standard, dimension, class, material and coating, agree minimum order quantity, packaging and lead time, and clarify any material certificate for strength or traceability. This is general information, not legal or technical advice.
