Fasteners for industrial supply
Bolts, nuts, studs and washers for assemblies. Metalex can discuss grade, form, finish, dimensional tolerances, documentation and packing with your procurement team. Confirm stock and delivery against your purchase specification.
Grades to ask about
Material grades are confirmed for the precise product and service. State the required standard and grade when enquiring.
Ordering checklist
State the grade and material standard, precise dimensions and tolerances, surface finish, quantity, certificate and delivery destination. Size range and stock are confirmed against the current enquiry; no fixed inventory is implied. For safety-critical, pressure or corrosive service, include the design code and inspection requirements so the right item can be checked.
Catalogue reference: Fasteners
Catalogue nominal size: M5–M60. Listed forms: hex and square bolts, studs, eye bolts, threaded bar, Allen bolts, screws, nuts and washers. Specify thread, fastener material and property class; a flat-product grade alone does not certify a fastener.

Choose the right specification
Send the product type, applicable standard, grade or material, thread, size and length, quantity, inspection requirements and destination. We will confirm what can be sourced for the exact enquiry.
Finish / condition: State coating or passivation, strength class and inspection needed for the joint. Material and dimensional standards, tests and certificate type should be agreed for this product before ordering.
Fastener types
Ask for hex bolts, machine screws, nuts, threaded studs, washers and anchors by thread diameter and pitch, length, property class, dimensional standard and head style. For wet or chloride service, verify material grade and galvanic compatibility with the connected metal; "stainless" alone is not a fastening specification.
