Parts for Mtd 247-203B401 / 1997: Chain Case Assembly Parts

This hex washer screw is a genuine OEM replacement part for a variety of household and outdoor appliances. A hex washer screw is a self-piercing screw with an attached washer at the head of the screw. Self-piercing screws are quite sharp and feature a twin-lead thread to screw into a surface more effectively. The built-in hexagonal washer helps to balance weight and force throughout the connection and prevent breakage. Hex washer screws can become damaged over time through repeated stress or tension. Their threading can become stripped or the head can eventually snap off. Replacing a hex washer screw is simple as long as you have the right tool. The unique shape of the screw head makes it incompatible with a flathead or Phillips head screwdriver. Instead, replacing this type of screw requires a unique hex head screwdriver. This part is compatible with Yard Machines, MTD, Yard Man, Troy-Bilt, and Craftsman products and will fit lawn mowers, tractors, snowblowers, vacuums, and chippers. This is a high-quality replacement part sourced from the original manufacture and ships independently of any other hardware.
