11 best slotted washers
Slotted washers, also known as castle washers or cotter washers, are a type of flat washer used in fastening applications. They are characterized by having a slot or opening cut into the center of the washer, which resembles the turrets of a castle, hence the name. These slots are designed to accommodate a cotter pin or a split pin, allowing for secure locking of nuts or bolts in place.
Here are some key points about slotted washers:
Purpose: Slotted washers are primarily used for securing fasteners, such as bolts and nuts, in situations where vibration or movement might cause them to loosen. The cotter pin or split pin inserted through the slot prevents the nut from backing off the bolt, ensuring a secure connection.
Design: Slotted washers are typically made from metal, such as steel or stainless steel, and have a flat, circular shape. They have one or more slots cut into them, creating small tabs that can be bent over the protruding end of a fastener.
Installation: To install a slotted washer, you would place it over the threaded end of a bolt or stud and then insert a cotter pin or split pin through the slots. The pin is bent or folded back on itself to secure it in place, effectively locking the fastener.
Applications: Slotted washers are commonly used in various industries, including automotive, construction, and machinery, where safety and security are essential. They are often found in critical components like suspension systems, axles, and machinery where preventing loosening is crucial.
Advantages: Slotted washers are simple and reliable solutions for preventing fasteners from coming loose.They are easy to install and remove when necessary, making maintenance and repairs more accessible.
Variations: While the basic design of slotted washers is the same, there can be variations in terms of size, material, and the number of slots. These variations are chosen based on the specific requirements of the application.
In summary, slotted washers are flat washers with slots designed to accommodate cotter pins or split pins, making them a vital component in fastening systems where preventing the loosening of nuts and bolts is crucial for safety and stability.

User questions & answers
| Question: | Is there a hand held slotted punch for these paper brads |
| Answer: | I don’t know if these are non-GMO but they are a crappy product. They fall apart easily. I will never buy these again |
| Question: | Will these washers attract to a magnet |
| Answer: | Ingredients: Our pads are made of a combination of absorbent materials, polyolefins, adhesives, and a silicone-coated paper. The top layer is a non-woven polyolefin cover sheet. The absorbent materials consist of TCF (totally chlorine free) wood pulp, and Lysorb, an absorbent gel. Lysorb, also known as SNAP (super absorbent natural polymer), is a polysaccharide derived from wheat. Polysaccharides are complex sugars found in many natural substances, like the fibers of cotton, wood, and wheat. |
| Question: | Does the box contain 100 pieces? Some reviewers say there are not |
