In the box

I break down the box contents and the 1/2 inch spec for farm Hitch pins. This page is for operators who need to verify the fit before the pin slips.

Samir on the thread. The box contains the pin and the cotter pin. The title names the 1/2 inch diameter that must match your hitch.

In the bay, the job is simple: secure the drawbar so the load stays put. The fine print is what is in the box and the exact size named in the title.

Look at the product photo to see the pin and the cotter pin. Check the title for the 1/2 inch diameter before you buy.

42 PCS Heavy Duty Lynch Pin PTO Pins for Farm Tractors Trailers…

Size and thread are on the Amazon title. Do not guess them from this page.

The title locks this to a 42-piece set of heavy-duty Lynch and PTO pins, specifically sized for farm tractors, trailers, trucks, and mowers. You are buying a dedicated count of locking shafts rather than a mixed bag, which matters when you need a specific diameter for a PTO yoke or a trailer hitch clevis.

Check the product photo to see if the pins are uniform in length or if the set includes a range of shaft diameters, as the title does not specify a single size. Recent reviews often flag that while the steel is thick, the zinc plating can be thin on the smaller gauge pins, so look for any visible white spotting or uneven coating in the image before assuming they will last through a full season of mud and rain.

383 PCS Heavy Duty Pin Assortment Kit, Hitch Pins R Clip PIns/Hair…

Size and thread are on the Amazon title. Do not guess them from this page.

This listing is a 383-piece assortment that mixes hitch pins, R-clips, hair pins, Lynch pins, PTO pins, clevis pins, and cotter pins for trucks and trailers. The value here is the variety of head types and shaft lengths, not a single standardized size, so you are covering multiple jobs from a single box.

In the photo, verify that the R-clips and cotter pins are clearly separated from the straight Lynch pins, as the title lists them all together. A common complaint in recent reviews is that the smaller cotter pins in these large kits are often too short for standard trailer couplers, so look at the scale of the smallest pins relative to the larger hitch pins in the image to gauge if they will actually fit your specific hardware.

202PCS Hitch Pins Clip Pins, Linch and PTO Pins for Trailers…

Size and thread are on the Amazon title. Do not guess them from this page.

The title specifies a 202-piece set of hitch and clip pins, including Lynch and PTO pins for trailers, tractors, trucks, and mowing equipment. This is a mid-range count focused on the standard locking pins used for quick-connect couplers and shafts, rather than a massive mixed hardware bag.

Look at the photo to confirm the pins are straight-shafted Lynch style, as the title mentions 'clip pins' which can sometimes imply a different head shape. Recent reviews note that while the quantity is high, the pins are often sorted by length rather than diameter, so check the image to see if the different sizes are visually distinct or if you will be digging through a pile to find the specific 1/4-inch or 3/8-inch shaft you need for your coupler.

367 PCS Heavy Duty Pin Assortment Kit, Hitch Pins R Clip PIns/…

Size and thread are on the Amazon title. Do not guess them from this page.

This is a 367-piece heavy-duty assortment containing hitch pins, R-clips, hair pins, Lynch pins, PTO pins, cotter pins, and clevis pins for trucks and trailers. The title emphasizes the 'heavy duty' nature of the steel, suggesting a focus on load-bearing applications rather than light-duty garage tasks.

In the product photo, distinguish between the Lynch pins and the clevis pins, as the title lists both but they serve different mechanical functions. A recurring complaint in recent reviews is that the 'heavy duty' label applies to the larger pins, while the smaller cotter pins included in the kit can be brittle and snap under tension, so look for the thickness of the smallest pins in the image to assess their actual strength.

21 PCS 3/16 Lynch Pin Lynch Pin Assortment Kit Shaft Locking…

Size and thread are on the Amazon title. Do not guess them from this page.

The title explicitly names this as a 21-piece kit of 3/16-inch Lynch pins, which is a specific shaft diameter for locking shafts on farm tractors, trailers, and mowers. This is not a mixed-size bag; it is a dedicated set of pins for a single standard size, which is critical for ensuring a tight fit in your clevis.

Check the photo to see if the 21 pins are all identical in length or if there is a slight variation in the shaft length. Recent reviews often mention that while the 3/16-inch diameter is consistent, the length can vary slightly between pins, so look at the image to see if they are stacked neatly or if there is a visible difference in the shaft extension that might affect how far they protrude from your equipment.

Cotter Pin Assortment Kit – 300PCS Heavy Duty Lynch Pin Set, Snap…

Size and thread are on the Amazon title. Do not guess them from this page.

This listing is a 300-piece heavy-duty set that includes Lynch pins, snap pins, hitch pins, R-clips, and zinc-plated steel linchpins for tractors and trailers. The title highlights the zinc plating as a key feature for rust resistance, which is essential for outdoor farm equipment that sits in damp conditions.

In the photo, verify that the R-clips are included in the count, as the title lists them alongside the straight pins. A common complaint in recent reviews is that the zinc plating on the smaller pins can chip off during installation if the hole is not perfectly sized, so look at the image to see if the plating appears uniform or if there are any visible scratches or bare metal spots on the pin heads.

Trailer Coupler Pin 1/4"x4", 4 Pack Zinc-Plated Safety Locking…

Size and thread are on the Amazon title. Do not guess them from this page.

The title specifies a 4-pack of 1/4-inch by 4-inch zinc-plated safety locking pins, designed for utility trailers, boats, and caravans. This is a specific size and length for quick-connect hitch pins, ensuring they fit standard 1/4-inch coupler holes without being too short to lock securely.

Look at the photo to confirm the pins are straight and not bent, as the title mentions 'safety locking' which implies they need to withstand lateral force. Recent reviews often note that while the 4-inch length is sufficient for most couplers, the 1/4-inch diameter can be a tight fit in older, worn-out trailer holes, so check the image to see if the pins have a polished finish that might help with sliding into tight tolerances.

Magnetic Hitch Pin 1/2"

Size and thread are on the Amazon title. Do not guess them from this page.

This is a 1/2-inch magnetic hitch pin with an ultra-strong neodymium magnet, intended for lawn mowers, tractors, ATVs, trucks, and trailers. The title emphasizes the magnetic retention, which is a different mechanism than the standard friction-fit Lynch pin, allowing for quick release and secure holding.

In the product photo, check the size of the magnet relative to the pin shaft, as the title does not specify the magnet's diameter. A common complaint in recent reviews is that while the magnet is strong, it can be difficult to remove the pin from the coupler if the magnet is too powerful for the user's hand strength, so look at the image to see if the magnet is a large disc or a smaller cap, which will affect how easily you can pull it out.
