1/4-20 Hex Nut
Genuine Husqvarna part
By: Husqvarna
Part Number: 586668901

This 1/4-20 hex nut has a great variety of uses on lawn and landscaping equipment. As a lock nut, it can be tightened and retains its grip, even without the use of a washer. This particular piece of hardware appears in many connective points on push mowers, zero-turn mowers, riding mowers, tillers, lawn tractor implements, and other types of equipment manufactured by Husqvarna, Poulan, Jonsered, and Weed Eater. For instance, with MTD mulching mowers, these hex nuts are used to secure the mower housing to the manifold of the mower. More than just with gasoline-powered lawn tools, these versatile nuts are also found on handheld tools like impact wrenches and tools driven by compressed air. Hex nuts bind tightly with their locking grip and seldom come off. The more likely scenario, especially since so many are used in manufacturing and by power tools, is that these nuts will become lost in the course of maintaining, cleaning, and repairing mowers and other equipment. For this reason, it's always important for the user to purchase more than the anticipated number needed. Make sure also to purchase hex nuts like these that are OEM certified and guaranteed.

Screw
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 690837

This is a replacement screw that can be used on various types of lawn and garden equipment. The type of equipment will affect where the screw is used on the tool. A screw is used to attach various components together so nothing comes loose while the tool is in use. It can also be used with a nut. It's best to choose a nut that has the same finish and threading as the screw.A screw can be damaged in many ways. If this occurs, it will need to be replaced. Corrosion, wear and tear, extreme stress, and high temperatures can all cause a screw to fail. Inspecting the screw can indicate whether it will need to be replaced. Use a screwdriver to take off the old screw, or use a pair of pliers if the screw has become stripped. Replace it with a new screw.This is an authentic OEM replacement part sourced directly from the manufacturer. Each screw is sold individually. The component is designed for use with lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, edgers, chainsaws, generators, and wood chippers manufactured by Briggs & Stratton, Simplicity, Toro, MTD, Cub Cadet, Lawn-Boy, Homelite, and Murray.
