Carbon Steel 4.8 Grade Castle Nut / Slotted Hex Nut
Product Description
Carbon Steel 4.8 Grade Castle Nut / Slotted Hex Nut / Hex Slotted Nut
A castle nut, also known as a slotted nut or castellated nut, is a type of fastener with notches cut into one end. The name comes from its resemblance to the crenellations on a medieval castle's wall. It is commonly used in applications where a secure, non-vibrating connection is needed. The bolt or axle has one or two holes drilled through its threaded end. The nut is tightened properly and then rotated to align the nearest slot with the hole in the fastener. Once aligned, it is secured using a split pin, R-clip, or safety wire. This makes it a reliable locking mechanism. Castle nuts are typically used in low-torque applications, such as securing wheel bearings or other mechanical components that require periodic inspection and re-tightening.

Acrylic tunnels are mostly used in aquariums, which are convenient for watching fish, and make people feel like they are there. Technically, our factory adopts acrylic one-time pouring sheet, cuts the acrylic slab according to the required size, and uses a customized mold to heat-bend the acrylic sheet into the arc panel needed by the acrylic tunnel. Moreover, our factory can apply arc seamless splicing technology at the corner of the acrylic tunnel to connect multiple tunnels into a whole without gluing, which greatly improves the aesthetics of the acrylic tunnel.
