About this item

  • Precision-Engineered for Non-Standard Fasteners: Specifically designed for pentagonal bolt heads, this all-steel penta wrench (Socket Penta Wrench) features an ergonomic T-handle design (T Handle Penta Wrench) to deliver optimal torque transmission. Ideal for pad-mounted transformers, secondary bases, and utility equipment requiring specialized fastening solutions.
  • Industrial-Grade Dimensions & Durability: With a 5.69" extended T-bar grip and 1.25" outer diameter socket, this heavy-duty lineman’s wrench ensures secure engagement on 0.97" inner diameter pentagonal bolts. Machined to ±0.02" tolerance for reliable performance in grid maintenance and curb box operations (Penta Curb Box Key).
  • Forged for Extreme Conditions: Constructed from hardened high-carbon structural steel, this corrosion-resistant tool outperforms standard alloy wrenches with 3x lifespan. Engineered to withstand moisture, chemical exposure, and repetitive stress during meter box cover installations (Tool Meter Box Covers Key) or valve adjustments.
  • Multi-Application Versatility: Compatible with utility meter curb boxes (Extension Curb Box Wrench), protective shut-off valves, and industrial enclosures. Functions as both a meter curb box key wrench and a heavy-duty torque amplifier for electrical/mechanical systems. 
  • Ergonomic Field Operation Design: The bidirectional T-grip configuration minimizes hand fatigue during prolonged use. Knurled handle texture enhances control in oily/wet environments. Recommended with cut-resistant gloves for safe operation in confined spaces.

This is a solid, substantial tool with good weight. The large T-handle provides excellent leverage, making it great for tackling stuck latches. It feels durable and up to the task. I recommend it.

This wrench for 5-sided bolts does what it's supposed to do. No moving parts, but heavily cast, it weighs in at nearly a pound. Fits the bolts on our in-ground vaults and transformer enclosures perfectly. I'd give the hot dipped galvanized finish a C-, as you can see from the photo, it's looking like there might be a little rust showing through, but again, it's not supposed to be pretty.
