What safety precautions should I take while working with fasteners?

Wear appropriate personal protective equipment like gloves and safety glasses and ensure that the fasteners are compatible with the materials being used.

How do I maintain my fastener assortments?

Store fastener assortments in a cool, dry place away from moisture and corrosive materials. Keep the containers sealed to prevent contamination.

What is the difference between a flat washer and a lock washer?

A flat washer is used to distribute the load of a fastener over a larger area, while a lock washer is used to prevent the fastener from loosening.

What is the difference between a hex nut and a lock nut?

A hex nut is a standard nut with six sides, while a lock nut has a built-in locking mechanism that prevents it from loosening.

What is the difference between coarse and fine thread fasteners?

Coarse thread fasteners have fewer threads per inch and are used for general purpose applications, while fine thread fasteners have more threads per inch and are used in applications where greater holding strength is required.
