Product Overview
This rectangular loop locking pin is a 45# steel agricultural machinery connecting pin designed for compatible linkage, hitch, pivot and attachment assemblies. It combines a flat-sided pin body with a rectangular wire retaining loop. The visible loop is connected to the pin assembly and provides a practical anti-loss arrangement during installation, removal and routine equipment service.
The pin is intended to pass through aligned holes or connection points and retain compatible agricultural machinery components. Its flat body and retaining loop make it different from a plain cylindrical pin or a separate loose clip. Exact dimensions, working length, hole fit and load direction are not specified in this page and should be confirmed from the equipment model, existing part, drawing or sample.
Key Features and Benefits
Integrated rectangular retaining loop: The visible wire loop stays with the pin assembly and can help reduce the risk of misplacing a separate retaining piece during field service.
Flat-sided pin body: The broad flat body is suited to connection arrangements that require a defined seating or retaining position, subject to fitment confirmation.
45# steel construction: The stated material is 45# steel. It is a commonly used carbon steel option for general mechanical connection components; the required strength, wear behavior and service suitability depend on the joint design and operating conditions.
Service-oriented design: The loop form provides a visible handling point for installation and removal where the surrounding equipment allows access.
B2B replacement supply: Suitable for stock planning by agricultural machinery manufacturers, parts distributors, repair workshops and engineering contractors.
Applications
This locking pin can be reviewed for compatible tractors, three-point linkage systems, plows, cultivators, seeders, planters, harrows, balers, mowers, trailers and other agricultural implements. Typical uses may include securing linkage parts, retaining a hitch or pivot connection, joining brackets and supporting removable attachments.
It may also be considered for compatible landscaping, construction or material-handling equipment when the pin profile, hole arrangement, working length and retaining method are confirmed. No specific brand or model compatibility is claimed without equipment information.
For manufacturers and distributors, the rectangular loop pin can be included in replacement-part programs or service inventories. Repair shops and contractors can use the pin as a replacement option when the original connection uses a similar flat-sided body and attached loop arrangement.
Selection and Fitment Factors
Check the following points before ordering:
Pin diameter, width, thickness and effective working length.
Shape and condition of the mating holes or connection brackets.
Required seating direction for the flat-sided body.
Space available for the rectangular retaining loop during installation and operation.
Shear, bending, vibration, impact and repeated movement at the joint.
Exposure to soil, moisture, corrosion and abrasive contamination.
Whether the pin is fixed, pivoting or removed regularly for implement changes.
A pin that looks similar may still be unsuitable if the body profile, hole alignment, working length or loop clearance is different. Load capacity and service life must be assessed from the complete joint rather than from the material name alone.
Wear, Load and Maintenance Considerations
The pin body and retaining loop may experience different contact conditions. The main pin section should be checked for scoring, bending, excessive clearance, corrosion and local deformation. The loop should be checked for bending, cracking, separation or loss of its intended retaining position. Repeated side loading, misaligned holes, insufficient lubrication or a worn bracket can accelerate wear on the connection.
Before installation, isolate the machine, lower supported implements safely and follow the equipment manufacturer's service procedure. Clean the mating holes and compare the replacement pin with the approved part or sample. Do not force the pin through misaligned or damaged holes. Confirm that the flat body is seated correctly and that the retaining loop is positioned without interference from moving parts.
During maintenance, inspect the complete joint rather than replacing the pin alone. If the hole is oval, cracked or excessively worn, the bracket or connected component may also require service. Replace a deformed or damaged retaining loop and remove any pin that no longer provides the required fit.
Stock Supply and Compatibility Support
This product is suitable for B2B purchasing where stock availability, repeatable replacement supply and practical fitment support are important. Buyers can request availability for the required configuration and quantity for production service, distributor inventory, repair stock or field projects.
For compatibility review, provide the equipment brand and model, pin location, existing pin, key dimensions, installation photo, drawing or sample. Also indicate the expected load direction, movement frequency and retention arrangement. These details help distinguish this rectangular loop locking pin from other agricultural connecting pins and reduce the risk of an incorrect replacement.
Custom Specification Support
The main purchasing focus is the available configuration, but specification support can be considered for dimensions or fitment details that are not confirmed from the product image. Possible review items may include pin body dimensions, effective length, flat-body geometry, loop clearance and related retention requirements. Any unlisted size or structural change should be confirmed from a drawing, sample or equipment information before production.
OEM/ODM support may be discussed for customer-approved agricultural machinery component specifications. This wording refers to specification support and does not imply original-brand identity, authorization or certification.
Bulk Ordering
For a bulk quotation, send the required quantity, material requirement of 45# steel, equipment application, drawing or sample, and requested delivery configuration. Manufacturers can use the pin for compatible assembly programs, distributors can build replacement inventory, and repair teams can source repeat parts for planned maintenance.
Stock status, available quantity and fitment should be reconfirmed for each order. The final selection should be based on the approved dimensions and joint requirements, not on a general machine category or product appearance alone.
FAQ
It is a 45# steel connecting and retaining pin for compatible agricultural machinery joints, such as linkage, hitch, pivot and removable attachment assemblies.
The visible product combines a flat-sided pin body with an attached rectangular wire retaining loop, providing a connected anti-loss arrangement rather than a separate loose clip.
No universal compatibility is claimed. Confirm the pin position, mating-hole dimensions, effective length, seating direction and loop clearance with an existing part, drawing or sample.
Yes. Bulk supply can be reviewed for manufacturers, dealers, repair workshops and engineering contractors according to the required configuration, quantity and application.
Check the mating holes, body fit, working length, flat-body seating, loop clearance and condition of the connected components. Do not install the pin into cracked, oval or misaligned holes.
