This is a flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.

This hex screw and lock washer are commonly used with lawn mowers and other small engines to secure a motor to the housing of the equipment. It is machined in such a way that it binds the manifold and frame permanently. There are occasions when these bolts have to be removed, typically when major repairs are performed on the engine. In those cases, users often find it advisable to replace the hex bolts and washers with new ones. It happens as well that these screws are so tightly fastened that they cannot be unscrewed and must be cut off. In those cases, it is necessary to replace the original screws. These replacement screws and lock washers are genuine OEM certified replacements that are manufactured to be identical to the hardware they are replacing. In addition to mowers, these hex screws are used to secure engines to devices such as log splitters, edgers, shredders, trimmers, and snowblowers. This screw is compatible with devices made by Husky, Yard-Man, Cub Cadet, Troy-Bilt, Ryobi, Bolens, and Yard Machines.

This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.

A flange nut's unique wide flange design distributes the nut's pressure over the part it is securing. In return, it creates an even fastening surface, which reduces part damage and nut loosening. This one-piece all-metal fastener has a lock nut version that features a protruding circular flange. This drastically increases bearing surface, compatibility either for irregular or oversized holes, and surface tension reduction. Flange lock nuts are the preferred type of fastener for many lawnmower models because it can provide better fastening than regular screws, which are known to loosen under extreme vibration. However, it’s important to know that flange lock nuts are susceptible to wear and tear due to constant vibration exposure. It is essential to replace the broken flange lock nut immediately to prevent serious damage to the lawnmower. The MTD 712-04063 Flange Lock Nut OEM replacement can be used with Craftsman, White Outdoor, Yard Machines, MTD, or Columbia lawnmowers. It is a genuine or OEM MTD replacement part that measures 5/16-18. It is threaded and requires the use of a wrench. This replacement flange lock nut is sold individually. An MTD bolt carriage may also be needed and is sold separately.
