This black surface-treated plow bolt is an agricultural replacement fastener for compatible plows, soil-working implements and farm machinery assemblies. Its visible structure includes a broad load-bearing head, a square neck below the head, a threaded shank and a matching nut. The square neck helps resist rotation when the bolt is installed through a compatible mounting hole, while the threaded shank secures the assembled wear part or implement component.
The black finish gives the fastener a uniform dark appearance and supports applications where the buyer requires a black agricultural bolt with additional surface protection. The exact treatment chemistry, coating thickness, salt-spray result and service life depend on the selected process and should be specified according to the application requirements.
Broad bearing head: The wide head distributes clamping force over the mounted component and provides a visible contact surface.
Square neck: The square neck section is designed for engagement with a compatible square mounting hole to help limit bolt rotation during tightening.
Threaded shank: The threaded section accepts the matching nut and allows the assembly to be clamped to the implement.
Matching nut: The pictured product is supplied with a hex nut. Nut grade, thread class and washer configuration can be specified for the intended assembly.
Material options: Carbon steel, alloy steel or another specified material can be selected according to the drawing, sample and required mechanical properties. No fixed material grade is assumed for every size.
A typical black finishing route may include surface cleaning and preparation, black surface treatment, drying or curing, and final inspection of appearance and thread condition. The exact sequence depends on the selected black oxide, black phosphate, black coating or other agreed finishing system.
Key benefits of the black finish include:
dark, uniform appearance for agricultural replacement parts;
additional surface protection for handling, storage and general working environments;
improved product identification when black-finished fasteners are specified by the equipment buyer;
compatibility with metric, imperial and custom fastener programs when the finish is applied after the required geometry is produced;
a practical finishing option for plow bolts used in soil-contact equipment, subject to the selected process and operating conditions.
The black finish should be selected together with the material, lubrication condition, thread fit and environmental requirements. Corrosion resistance and wear performance should be evaluated against the agreed process specification rather than inferred from color alone.
Metric and imperial configurations can be supplied according to the required assembly. Common purchasing formats include M-thread plow bolts, inch-thread plow bolts, metric dimensions in millimetres and imperial dimensions in inches. Typical inquiry descriptions may include diameter, thread pitch or thread form, overall length, threaded length, head diameter, head thickness, square-neck size and nut type.
Available specification programs may include:
metric sizes such as M10, M12, M14, M16, M20 and M24;
imperial sizes such as 3/8 in, 1/2 in, 5/8 in, 3/4 in, 7/8 in and 1 in;
standard and fine thread requirements where applicable;
non-standard diameters, lengths, head dimensions and square-neck dimensions;
special thread forms, partial-thread or full-thread configurations;
bolt-and-nut sets matched to the buyer's existing implement hardware;
plow bolts made to a technical drawing, physical sample or confirmed replacement-part dimensions.
The sizes above describe common procurement search formats and do not represent one fixed stock configuration. The required diameter, length, thread, head geometry, material, nut and finish can be produced to the customer's drawing or sample.
The plow bolt is intended for compatible agricultural equipment and replacement assemblies, including:
moldboard plows and reversible plows;
plow shares, mouldboards and other replaceable plow wear parts;
disc harrows and soil cultivation equipment;
cultivators, field cultivators and tillage implements;
farm machinery frames, brackets and replaceable working components;
agricultural machinery repair and spare-parts programs.
Exact equipment compatibility depends on the mounting-hole geometry, bolt diameter, square-neck dimensions, thread, clamping length and working load. Use the equipment model or original bolt sample to select the replacement specification.
These black plow bolts are suitable for agricultural machinery manufacturers, farm equipment dealers, replacement-parts distributors, repair workshops and procurement teams sourcing repeat fastener programs. They can be used for production assembly, field replacement, maintenance inventory and custom agricultural implement projects where a dark surface finish and drawing-based dimensions are required.
Quality checks can be arranged around the buyer's technical requirements and may include:
incoming material and dimensional review;
head, square-neck and threaded-shank inspection;
thread gauge and nut-fit inspection;
visual inspection of black finish consistency;
coating or surface-treatment checks according to the agreed process;
sampling inspection of dimensions, appearance and packaging identification.
Inspection items, sampling level, material documentation and test reports can be specified in the purchase agreement. No certification or fixed test value is included without a customer-approved requirement.
Plow bolts can be packed in bulk cartons, inner boxes, labeled bags, trays or other agreed packaging formats. Packaging labels can include the model, size, thread, quantity, finish and batch reference when required. Delivery and packing details can be arranged according to order quantity, customization level and the buyer's logistics requirements.
Custom production is available for diameter, overall length, threaded length, thread type, head diameter, head thickness, square-neck size, material option, nut configuration and black surface-treatment specification. Non-standard plow bolts can be developed from a technical drawing, physical sample, original-part measurement or confirmed equipment requirement.
For a quotation, please provide the required metric or imperial size, diameter, thread, overall length, threaded length, head and square-neck dimensions, material preference, black surface-treatment requirement, nut configuration, quantity and application. A drawing, sample or clear photo of the existing plow bolt will help match the replacement specification efficiently.
