They are often paired with machine screws or bolts to join two or more pieces of material together.

Frequently Asked Questions (FAQs)

1. Why use barrel nuts?

Barrel nuts are used to ensure maximum security when clamping two materials together. They are internally threaded parts that are commonly used for clamping two pieces of material together with machine screws. Barrel nuts are versatile and can be used in various applications such as playground equipment, ironmongery, and signage.

2. How do you use a barrel nut in bed?

To use a barrel nut in a bed, insert it into the hole on the side rail. Look for a circular hole near the end post and slide the nut into place. Rotate the barrel nut with a screwdriver so that the hole through the middle aligns with the bolt hole on the end post. Barrel nuts are typically used in wooden bed frames to securely join the rails and posts.

3. What is the strength of a barrel nut?

Barrel nuts can have different strength levels depending on the material used. For example, some barrel nuts made with Inconel 718 material have exceeded a tensile strength of 260 KSI, while those made with 4340 alloy steel have exceeded 220 KSI. The Titan Barrel Nut, in particular, has been tested to pass up to 50 cycles in torque tests, demonstrating its strength and durability.
