FAQ:

Q: What are thread adapters?

A: Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads. Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

Q: Can you use a standard wrench to tighten thread sizes?

A: Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench. Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Q: How do you increase the size of a thread?

A: Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench. Adapt threaded rods from inch to metric.

Q: What is a male-threaded adapter?

A: These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.
