Bolts & screws
Hex, socket, flange and machine screws in different grades and coatings. Thread, length, head and property class must be specified.
Product group 04 · Hardware
Industrial hardware and mechanical components, specified beyond the part number.
Fasteners and mechanical parts look simple until grade, thread, coating or tolerance is wrong. A lower unit price can disappear quickly when a batch fails inspection or does not fit the mating component. Make the variables explicit before comparing quotes.
Overview
Product overview.
We support standard hardware, replacement parts and customized mechanical components. Material and dimensional requirements are confirmed against the drawing or sample before supply.
This page explains the common product families, the information a supplier needs and the purchasing questions worth resolving before an order. Specifications vary by model and supplier; all technical data is subject to confirmation upon inquiry.

Grade, thread standard, length, coating and inspection requirements are part of the specification. A generic product name is not enough for a reliable quotation.
Product families
Common types and what distinguishes them.
Nuts & washers
Matching nuts, flat and spring washers. Material and coating should be compatible with the bolt and environment.
Anchors & clamps
Concrete anchors, pipe clamps, brackets and mounting hardware. Base material, load and installation conditions matter.
Bearings
Ball, roller and selected mounted bearing units. Bore, load, speed, sealing and clearance must be confirmed.
Mechanical components
Shafts, bushings, pins, linkages, springs and other metal parts made to drawing or sample.
Replacement parts
Obsolete or hard-to-find hardware identified from dimensions, photos, nameplates or samples.
Custom fasteners
Non-standard threads, lengths, heads and materials. Tooling, minimum quantity and inspection requirements should be discussed early.
Specifications vary by model and supplier; all technical data is subject to confirmation upon inquiry.
Custom requirements
Standard product not enough?
Available supply options may include standard products and customized specifications, subject to project requirements. Share a drawing, sample or performance requirement and we will review suitable manufacturing and supply options.
Discuss Custom RequirementsMaterials & standards
The details that change the quote.
The ranges below are common industry references, not a statement of stock or supplier capability. The applicable grade, standard and test requirement must be confirmed for the specific inquiry.
- Material grade
- Carbon steel, stainless steel, alloy steel, brass and selected materials. Property class and corrosion resistance must be stated.
- Thread and dimensions
- Metric or imperial thread, pitch, length, head type and tolerance. Confirm the mating part or standard.
- Coating and finish
- Zinc, zinc-nickel, hot-dip galvanized, black oxide, passivation and other finishes. Coating thickness and compatibility may matter.
- Inspection
- Dimensional checks, hardness, tensile requirements, plating thickness and sampling can be specified where required.
- Packaging and marking
- Bulk, bagged, kitted or labelled packaging. Traceability and marking requirements should be agreed before production.
- Standards
- DIN, ISO, ANSI/ASME, GB or drawing-specific requirements. The applicable standard must be stated rather than inferred.

Before you buy
Purchasing considerations.
Specify the full fastener
A bolt is not complete without grade, thread, length, head, coating and standard. Missing one variable can change the supplied part.
Check material compatibility
Stainless fasteners in a chloride environment or dissimilar metals in a joint can create problems that a unit price comparison will not reveal.
Define the inspection basis
State critical dimensions, hardness, plating and sampling requirements. Inspection should match the risk of the application.
Plan packaging and traceability
Bulk bags may be fine for standard parts; project kits and marked lots need a written packaging spec.

FAQs
Common questions about hardware & mechanical components.
Can you match an existing fastener?
Send dimensions, thread, grade, coating and photos. A sample is the most reliable reference. We will identify what information is missing before quoting.
Can you supply small quantities?
Standard items may have supplier minimums. Custom fasteners usually involve tooling and minimum production quantities; we will confirm before proceeding.
Do you supply material certificates?
Certificates can be requested where the selected supplier offers them. The required standard and scope must be stated in the inquiry.
Can you source bearings by dimensions?
Yes, if bore, outer diameter, width, load, speed and sealing requirements are known. The original bearing designation or a clear photo helps.
Can you combine fasteners into a kit?
Kitting and labelled packaging can be discussed. The bill of materials, quantities, labelling and inspection requirements should be agreed in writing.
