This self-tapping bolt is an OEM replacement part that is sourced directly from the manufacturer. This self-tapping bolt is used to secure the silencer plate to the carburetor. The bolt taps its own hole as it is screwed into place. Using these bolts prevents the holes from being over-drilled or warped due to heat during shipment. The hole is the perfect size due to being tapped by the fastener.Self-tapping bolts create a tight fit and are a good choice for securing multiple layers of material. The holes do not have to be aligned before installation. The bolt makes the hole it needs through each layer. This makes it easier to disassemble and reassemble if necessary. Over time, exposure to the elements may cause the bolt to rust or corrode. If this happens, remove the damaged bolt and install a new one. This self-tapping bolt is made of heavy-duty metal and is sold individually. It is compatible with chippers, shredders, tillers, and other small engines manufactured by Cub Cadet, MTD, and Yard Machines.

This is a genuine OEM clamp sourced directly from the manufacturer. It is used in various lawn and garden machines to connect hoses to fittings. It is used to connect piping to water pumps, exhaust pipes to exhaust manifolds, and other similar applications. This connection prevents fluids or air from leaking from the hose. Clamps may be spring or screw/band clamps. Spring clamps require no tools to install and remove; however, the size must be more accurate than when using screw/band clamps. Screw/band clamps are adjustable and can be tightened or loosened. Screw clamps should be inspected periodically to ensure tightness and that the clamps have not rusted.Hose clamps are installed approximately 1/4 inch below the end of the hose. If two clamps are used, there should be 1/4 inch between the two bands. When using a screw clamp, loosen the screw with a screwdriver just enough to fit the clamp over the hose. If using a spring clamp, squeeze the clamp and hold it open. Slide the clamp over the hose and then attach the hose and clamp to the fitting. Slide the clamp into place at the joint and tighten. Do not overtighten. This brass-colored clamp is a spring clamp made of metal; it is sold as an individual unit. This clamp is compatible with many different types of pipes made by various manufacturers.

Exhaust piping connects to the muffler system on small engines. Replace if cracked, corroded, or damaged to restore proper exhaust routing and function.
