Keep the drawing.
Keep the thread.
Keep the lot.

High-strength machinery fasteners need an exact joint definition. Weishun’s catalogue spans metric and inch references; a class label alone cannot settle fit, tightening or batch acceptance.

Apply the hot-forging statement to fasteners

Weishun identifies 宁波市鄞州伟顺工程机械有限公司 at Chengyao Road, Hengxi, Ningbo. Its introduction describes manufacture of high-strength machinery fasteners using hot forging, with plow, track-shoe, segment and internal/external hexagon bolts for construction assemblies. [1]

Blade and corner fastening

Specify the plow/edge fastener against the joint drawing, including head seating and mating components. A high-strength class is not a head-geometry definition.

Track-shoe and segment fastening

Use the installed reference, thread and drawing together. Preserve catalogue suffixes until the supplier explains their geometry. Quote bolt and nut quantities separately.

Other advertised components

Washers, castings/forgings, wear strips, cutting edges and teeth appear in the wider catalogue. Their presence does not establish that they share the fastener production route or are included in the same package.

The useful detail is in the thread designation

Do not shorten the order to “track bolt”.

The dedicated catalogue lists 2A3223 as 1/2″ × 20 UNF × 47 and 101-32-11210 as M12 × 1.5 × 40. It also includes UNS references and F/D suffixes without a readable definition. [2] A visually similar metric and inch bolt is not an interchangeable alternative.

Ask for the controlled drawing

Require thread system, diameter/pitch, tolerance, head/shoulder dimensions and the meaning of the length/suffix. Confirm the mating nut’s own designation and drawing. Entries in the same family table are not automatically compatible pairs.

State coating and lubrication condition beside the mechanical specification. Tightening requirements belong to the approved joint documentation, not a generic torque calculated from a marketing grade. The product guide includes a searchable subset of directly checked catalogue entries.

Separate a property class from batch acceptance

Weishun offers 10.9/12.9 or customer-designated material and says its ordinary supply is largely 12.9 bolts with grade-10 nuts. The page also contains tensile/hardness summaries. [2] These are supplier statements, not a test report or an approved pairing for your joint.

  1. 1

    Define the governing specification

    Identify bolt and nut standards separately, including thread scope and geometry. Do not apply a metric standard indiscriminately to every inch entry.

  2. 2

    Agree the inspection evidence

    Request material and heat-treatment traceability, agreed property/dimensional tests and a report linked to the delivered lot. Define sampling and acceptance rather than accepting an unreferenced certificate.

  3. 3

    Preserve identity through stock

    Agree package labels, part reference, drawing revision and lot identification. Keep replacement-stock records tied to the approved joint and matching components.

ISO’s publisher abstracts distinguish bolt/stud and nut mechanical-property scopes. ISO 898-1 does not define torque/clamp-force or fatigue performance. [3] [4] These boundaries are reasons to specify the actual joint; citing the standards does not verify Weishun’s conformity.

A certification intention is not a certificate

The company text says it will follow the ISO9001 system and aims to complete certification. [1] The statement does not establish current certification. We assign no certificate badge, and unrelated newer news dates do not update that wording.

If a quality-system certificate is a purchase condition, obtain the certificate, legal holder, covered site, scope, issuer and validity. This profile has no independent factory audit, calibration review or delivered-lot test result. Use those actual records for qualification rather than promoting the website’s aspiration into approval.
