Th-350 Transmission: Bolt Sizes

The TH-350 pan transmission bolts are available in sets of 13 bolts and 13 washers. The bolts are 5/16-18 standard thread bolts with a flange head and are compatible with TH350 or TH400 transmissions. The overall length of the bolts is 0.95 with a 0.75 under-head length. The bolts are made from durable steel with a chrome finish or are zinc-coated for corrosion resistance.

The TH350/TH400 transmission pan bolt set includes 13 bolts

The bolt set is designed for use with GM Turbo 350 and GM Turbo 400 transmission pans. The overall length of the bolts is .95", with a .75" under-head length and a 5/16"-18 thread pitch. The set includes 13 washers.

The TH350/TH400 transmission pan bolt set is made from heavy-duty, high-strength, grade 10.9 bolts. They are zinc-coated for long-lasting corrosion protection. The bolts are manufactured using premium-grade, USA-produced materials and are designed to fit TH-350 and TH-400 automatic transmission oil pans.

The bolts are 5/16-18 standard thread

The TH-350 pan transmission bolts are 5/16-18 standard thread bolts with a flange head. This is the most common size for these bolts, and they are compatible with both TH350 and TH400 transmissions. The bolts are typically sold in sets of 13, which is the number required to secure the transmission pan.

The 5/16-18 standard thread size refers to the diameter of the bolt and the density of the threads. In this case, the bolt has a diameter of 5/16 inches, and there are 18 threads per inch. This is a common size for bolts, and you may be able to find them at your local hardware store or online.

When purchasing TH-350 pan transmission bolts, it is important to buy the correct size to ensure a secure fit. The bolts should also be made from high-quality materials to withstand the stress and vibration of the transmission. Some bolts are also zinc-coated to provide long-lasting corrosion protection and prevent the threads from seizing.

In addition to the bolts, you may also need to purchase washers. Some TH-350 pan transmission bolts come with washers, while others do not. If you already have washers, make sure they are the correct size and compatible with the bolts you are purchasing.

The bolt kit is compatible with TH350 or TH400 transmissions

The bolt kit is also available in zinc. This option includes 13 zinc-plated steel bolts and 13 zinc-plated washers. The zinc coating provides long-lasting corrosion protection and prevents threads from seizing. These bolts are compatible with GM Turbo 350 and GM Turbo 400 transmission pans.

Another option for the bolt kit is a set of heavy-duty, high-strength, grade 10.9 bolts. This set includes 13 bolts with flanged heads, so washers are not needed. These bolts are also zinc-coated for corrosion resistance and are compatible with TH350 or TH400 transmissions.

The bolt kit is designed to secure your transmission pan. It is important to select the appropriate bolt kit for your vehicle's specific transmission pan.

The bolts are zinc-coated for corrosion resistance

The bolts are zinc-coated to protect the steel from corrosion. Zinc is a popular choice for this purpose because it is abundant and affordable, and it provides good corrosion resistance. In fact, nearly half of all zinc produced is used for this purpose.

Zinc coating acts as a barrier that keeps moisture from reaching the surface of the coated object. This is important not only outdoors but also in indoor industrial or manufacturing environments, where moisture can enter through ventilation ducts. Zinc also forms corrosion byproducts that significantly reduce the corrosion rate of ferrous metals. These byproducts, known as zinc patina, serve as an additional protective barrier.

Zinc coating also serves as a sacrificial coating. In other words, it will always tarnish and corrode first, even when a scratch or cut exposes the steel underneath to air or moisture. This is in contrast to coatings made of materials like paint or aluminium, where the corroding steel can reduce the coating's effectiveness over time.

Zinc plating is a common method of applying a zinc coating to fasteners like bolts. It involves electroplating, or adding a thin layer of zinc to the bolt through an electrical process. Zinc plating creates a thinner, more uniform layer of zinc than other methods like hot-dip galvanization, making it less likely to skew the fine tolerances of fasteners. It is also generally inexpensive and requires less raw zinc than hot-dip galvanizing.

However, zinc plating does have some drawbacks. The plating alone may not provide enough corrosion resistance in wet or high-humidity environments, and zinc is chemically susceptible to acids and alkalis. Additionally, there is a risk of hydrogen embrittlement, where the bolt absorbs hydrogen molecules during the plating process, which can cause cracking.

Overall, zinc coating provides a good level of corrosion protection for bolts, especially when compared to uncoated steel, and it is a popular and cost-effective choice for this purpose.

The bolt kit is also available in black

The black bolt kit is designed with attention to detail and precision, ensuring a perfect fit for your TH-350 transmission. Each bolt is crafted with high-quality materials and finished with a durable black coating. This coating not only enhances the appearance but also provides long-lasting protection against corrosion and wear.

One of the advantages of choosing the black bolt kit is its ease of installation. The kit includes everything you need for a straightforward and hassle-free installation process. The bolts are designed to securely fasten your transmission pan in place, ensuring a stable and reliable connection.

Additionally, the black bolt kit offers excellent value for money. It is a cost-effective option that delivers on both performance and style. Whether you're looking to upgrade the appearance of your transmission or simply need a reliable and durable solution, the black bolt kit is a great choice.

When it comes to maintaining your vehicle, having access to high-quality parts is essential. The black bolt kit for the TH-350 transmission is a testament to the attention to detail and craftsmanship that goes into automotive engineering. By choosing this option, you can be assured of a reliable and long-lasting solution that enhances the overall performance and appearance of your vehicle.
