Fixed Pin Spanner Wrench

The Westward 5RDZ4 is a fixed pin spanner wrench built from alloy steel with a black oxide finish. It is intended for technicians who need to tighten or loosen slotted collars, locknuts or bearing housings where a round pin engages the slot. The 3/16 in pin diameter and 2 in hook depth suit medium-sized industrial fasteners.

Pin and Hook Dimensions

The round pin measures 3/16 in diameter and 3/16 in length, while the hook thickness is 13/32 in and hook depth reaches 2 in. These fixed dimensions mean the tool fits only fasteners with matching slot width and spacing, so buyers who need adjustable pin spacing or a different pin diameter cannot use this model.

Manual Quick-Adjust Operation

The wrench uses a manual quick-adjust mechanism that lets the user slide the hook into position without extra tools. Because the pin size is fixed, the most common issue is discovering on site that the fastener slot does not match the 3/16 in pin, requiring a different spanner.

Questions about this item

Will the 3/16 in pin or 13/32 in hook need replacement later?

The alloy steel construction and black oxide finish resist wear, so the fixed pin and hook dimensions stay true without scheduled replacement.

What stops me from using this spanner continuously on stubborn fasteners?

The manual quick-adjust mechanism and 2 in hook depth limit leverage, so sustained force is capped by the tool's fixed geometry.

Does the black oxide finish get hot or slip during all-day use?

The finish stays cool because there are no moving parts generating friction, and the round pin shape maintains grip without heating up.
