Product Description
Crescent® Adjustable Black Oxide Construction Wrench
AT215SPUD — Spud Wrench with Tapered Tang — 1-1/2” Jaw Capacity
The Crescent AT215SPUD is a purpose-built construction wrench — commonly known as a spud wrench — designed for ironworkers, steel erectors, and anyone who needs to align bolt holes while simultaneously tightening fasteners. The round, tapered tang on the handle end slides into misaligned holes and draws them together, letting you pin the connection with one hand while the adjustable jaw works the nut with the other. It’s the kind of tool that earns its spot on your belt every single day.
Forged from heat-treated alloy steel with a black oxide finish, the AT215SPUD is built for the punishment of structural steel work. Black oxide doesn’t just look good — it provides a non-reflective surface that resists rust and corrosion while being easier to grip than polished chrome in wet or oily conditions. The 16” overall length delivers serious leverage, and the proportioned dimensions are engineered to maximize strength while keeping weight down to 2.35 lbs — critical when you’re working overhead or climbing steel all day.
The hex jaw opens to 1-1/2” (39mm) and grips fasteners on the flats to reduce slippage and rounding. A larger knurl provides tight jaw adjustment with minimal play, and the laser-etched dual scale (SAE and Metric) lets you ID fastener size at a glance. Meets or exceeds both ANSI and ASME specifications for adjustable wrenches, backed by Crescent’s full lifetime warranty.

Built for the Iron — Where the Spud Wrench Lives
The spud wrench is the signature tool of the ironworker. If you’re connecting structural steel, erecting towers, or assembling heavy equipment frames, this is the wrench that never leaves your belt. The tapered tang replaces the need for a separate drift pin on most connections, letting you work faster with fewer tools.
- Structural Steel Erection — align bolt holes on beams, columns, and gusset plates while tightening connection bolts in a single operation
- Tower & Antenna Work — essential for climbing crews assembling communication towers, wind turbines, and transmission structures
- Bridge & Highway Construction — heavy structural connections, guard rail assembly, and overhead sign structures
- Heavy Equipment Assembly — frame bolts, boom pins, and structural connections on cranes, excavators, and loaders
- Agricultural Structures — grain bin erection, barn framing, pivot irrigation assembly, and equipment shed construction
- Industrial Piping — flange alignment on large-diameter pipe runs where bolt holes don’t quite line up
Pro Tip: The black oxide finish won’t blind you with glare when working in direct sunlight, and it holds chalk marks better than chrome — handy for marking bolt patterns on steel.
