Track fasteners · Reference family, drawing-led order
Track-shoe bolts and nuts
A mixed metric and inch-thread fastener catalogue. Selecting a reference requires its controlled geometry, material/property specification and matching nut; neighbouring catalogue rows are not approved bolt/nut sets.
Keep the complete catalogue designation
Search this reviewed subset by reference, thread or suffix.
The manufacturer’s track-shoe page lists metric and inch-thread bolts and nuts together. The subset below is directly transcribed for procurement screening. It is not the complete catalogue, an interchangeability table or a set of approved bolt/nut pairings. [1]
10 reviewed references shown. Rows are separate entries.
| Reference | Catalogue designation | Selection question |
|---|---|---|
| 2A3223 | 1/2″ × 20 UNF × 47 | Confirm head, shoulder and final length convention. |
| 6V1792 | 3/4″ × 16 UNF × 61D | Preserve and define the D suffix. |
| 2M5657 | 1″ × 14 UNS × 75 | Keep UNS, rather than silently substituting UNF. |
| 101-32-11210 | M12 × 1.5 × 40 | Confirm controlled metric drawing and nut. |
| 79039443 | M18 × 1.5 × 55F | Obtain the F geometry definition. |
| 20Y-32-11210 | M20 × 1.5 × 56F | Keep the complete suffix and matching interface. |
| 9W3619 | M20 × 1.5 × 55D | A shared M20 pitch does not make geometry identical. |
| 195-32-61210 | M30 × 1.5 × 96 | Confirm the mating nut independently. |
| 9W3361 | M20 × 1.5 × (28.6 × 22) | Nut entry; bracketed dimensions need a drawing. |
| 195-32-61221 | M30 × 2.0 × (46 × 38) | Nut entry; its pitch differs from the M30 bolt above. |
The raw strings are kept intact. The readable source does not define F/D or every length/bracket convention. An M30 × 1.5 bolt and M30 × 2.0 nut in the same catalogue are not a matching pair. Do not purchase by diameter alone or by proximity in the list.
Resolve the shape as well as the thread
From the installed joint
Send the original part reference and drawing, or document the measured used part with wear condition. Identify thread system/pitch, head seating, shoulder and engagement requirements. Preserve the existing joint’s mating-part information.
From the supplier
Request the proposed bolt and nut drawings with revisions and tolerances, including suffix definitions. Ask for the length datum and bracketed nut dimensions rather than translating a catalogue shorthand into your own geometry.
A reference cross-match should return a controlled interface, not just a statement that a part is “for excavators”. If a different nut or finish is proposed, update the purchase definition and approved joint documentation together.
Specify bolt and nut properties separately
The supplier offers 10.9, 12.9 or customer-designated material and says normal stock is largely 12.9 bolts with grade-10 nuts. It also publishes a tensile/hardness summary. [1] That wording is not a lot test or a blanket approved pairing for every reference.
- Governing specificationWrite the bolt and nut standards, property/material requirements and thread scope separately. ISO’s metric mechanical-property scope cannot simply be assigned to all inch-thread rows.
- Condition and evidenceAgree finish/lubrication, material and heat-treatment traceability, dimensional checks, property test methods and lot-specific reporting.
- Installed jointObtain tightening requirements from the approved joint documents. Property class does not by itself establish torque, clamp force or fatigue performance.
The ISO 898-1 publisher abstract explicitly separates those excluded joint properties from its mechanical-property scope; ISO 898-2 covers nut properties separately. [2] [3] We do not claim supplier compliance or reproduce an unverified installation torque.
Keep the reference through receiving and stores
Match the received part reference, thread, drawing revision and finish to the order. Keep bolt/nut/washer quantities and lot identification visible on package records. Agree how inspection reports identify the actual batch so a generic certificate is not substituted for the purchase’s acceptance evidence.
Can I remove F or D when asking for an equivalent?
The catalogue does not define these suffixes. Keep them and obtain the supplier’s geometry explanation. Removing one can discard an unresolved difference.
Is the nearby nut row the correct mating part?
No pairing is implied. The catalogue includes different pitches for the same nominal diameter; require the controlled matched drawings.
