Spanner Wrench

Williams JHWWS-474 Adjustable Hook Spanner Wrench 4 Piece Set

A spanner wrench is a hand tool used to tighten or loosen pipe fittings as well as large bolts and nuts. It has a U-shaped jaw with teeth that fit into the grooves of the fastener, allowing for grip and torque to be applied. They come in various sizes and designs, such as adjustable spanners, ratcheting spanners, and combination spanners.

It’s important to note that manufacturers may have slightly different size specifications for their wrenches.

Spanner wrenches typically come in various finishes, including:

• Chrome plating: provides a shiny, rust-resistant finish and is common in most household and automotive tool sets.
• Black oxide: a dark, matte finish that provides added grip and improved rust resistance compared to untreated steel.
• Nickel plating: provides a bright, polished finish that is highly resistant to corrosion.
• Sandblasting: creates a matte, non-reflective surface that helps improve grip and provides a more industrial look.

The finish chosen can depend on personal preference, durability requirements, and the intended use of the spanner wrench.

There are several types of spanner wrenches, including:

• Adjustable spanner wrench: also known as a crescent wrench, it has a movable jaw that can be adjusted to fit different sizes of nuts and bolts.
• Fixed spanner wrench: has a fixed jaw with teeth that match specific sizes of nuts and bolts and is typically more precise than an adjustable wrench.
• Combination spanner wrench: has both a fixed and an adjustable jaw, allowing it to be used on various nut and bolt sizes.
• Ratcheting spanner wrench: has a ratcheting mechanism that allows the user to turn a fastener without removing and repositioning the wrench each time.
• Strap wrench: has a flexible strap that wraps around a fastener and provides a grip for tightening or loosening.
• Box-end wrench: has a closed-end that fits over the fastener, providing more torque and stability than an open-end wrench.
