Paramount PAR37112 Hex Key 1/4 Inch Long Arm Steel

Product Description

The PARAMOUNT PAR37112 is a long-arm hex key with a 1/4 inch hex drive, manufactured from steel for use in mechanical assembly, equipment maintenance, and fastener-drive applications. The long arm style provides extended reach into recessed fastener locations and delivers increased torque leverage compared to standard-arm keys. At 5.25 inches overall length, this tool is sized for professional use across a range of trade applications. Licensed HVAC technicians, plumbers, electricians, and general mechanical contractors rely on this type of hex key when working with set screws, cap screws, and socket-head fasteners in tight or deep cavities. The steel construction provides the durability needed for repeated, high-force use in the field.

This hex key is suited for both residential and light commercial service work where 1/4 inch hex fasteners are common. Typical applications include tightening or loosening set screws on motor shafts, fan hubs, valve stems, and equipment panels. The long arm configuration is especially useful when fastener access is limited by adjacent components or enclosure walls. Maintenance technicians working on HVAC equipment, pump assemblies, and electrical panel hardware will find this tool fits standard workflow without modification.

Key Features

• 5.25 inch overall length fits within the 4 to 6.9 inch range for mid-size hex keys
• Steel construction resists deformation under high torque loading
• Hex end type engages fasteners fully for reduced cam-out risk
• Inch measurement system; compatible with standard SAE fastener specifications

Compatibility

Designed for use with 1/4 inch hex socket-head cap screws and set screws conforming to inch-measurement standards across general mechanical and trade service applications.

Installation Notes

This tool is used by licensed trades and maintenance professionals for manual fastener driving. Before servicing equipment, de-energize electrical systems and relieve any system pressure per applicable safety procedures. Use the long arm end for torque application and the short end for fast turning in open-access situations. Inspect the hex key tip before use and replace if the drive end shows rounding or deformation that could damage fastener heads.
