3/8" Drive SAE 51/64" Penta-Socket - J.H. Williams

Part #: JHWBB-526

The J.H. Williams JHWBB-526 3/8" Drive SAE 51/64" Penta-Socket is engineered for professionals requiring precise and secure access to controlled-access and security fasteners. This specialized 5-point 51/64 socket provides an exact fit for penta-head bolts, which are commonly found in utility, municipal, and industrial infrastructure where standard hex sockets are unsuitable due to their unique five-sided design.

Key Features

  • Precision 51/64" Penta Profile: Designed with a dedicated 5-point geometry, this 51/64 socket securely engages security fasteners on utility infrastructure, industrial enclosures, and cabinets, preventing cam-out and potential fastener damage.
  • 3/8" Drive System Compatibility: Integrates seamlessly with standard 3/8" drive ratchets, torque wrenches, and extensions, allowing for efficient use within existing professional tool kits without requiring specialized adapters.
  • SAE-Accurate Machining: Precisely machined to SAE dimensions, ensuring a snug fit on 51/64" penta fasteners. This precision minimizes slippage, enhancing both operational safety and the longevity of critical security bolts.
  • Professional-Grade Durability: Manufactured by J.H. Williams, a trusted name in industrial tools, this socket is built for consistent strength and reliable performance in demanding shop, yard, or roadside environments.
  • Optimized Portability: Weighing approximately 0.18 lb, its lightweight and compact design ensures easy transport in service vehicles, tool bags, or belt pouches without adding unnecessary bulk.

Applications

The JHWBB-526 51/64" penta socket is an essential tool for accessing locked utility boxes, transformer cabinets, metering enclosures, and street lighting access panels that utilize 5-point security hardware. It is also well-suited for plant maintenance, industrial equipment access points, and public infrastructure where controlled-access penta fasteners are specified, such as on manhole covers, waterworks, and valve boxes. This tool is a practical choice for utility linemen, municipal maintenance crews, fleet service teams, and industrial technicians who regularly encounter these specialized bolts in their daily work. For fleet service teams, it addresses specific security hardware on commercial or municipal vehicles where these fasteners are sometimes employed.
