Paramount PAR37101 Hex Key Long Arm Protanium Steel

Product Description

The PARAMOUNT PAR37101 is a long-arm hex key designed for fastening and loosening hex socket fasteners in tight or recessed locations. The extended long arm provides increased reach compared to standard-length hex keys, making it well suited for confined spaces where a short arm cannot seat properly. Manufactured from Protanium High Torque Steel, the key delivers high torsional strength and resists deformation under heavy load. The overall length is 2-45/64 inches. This tool is used by HVAC technicians, plumbers, electricians, and general trade professionals for equipment assembly, panel work, and mechanical fastener service.

The PAR37101 is appropriate for residential and light commercial service work where hex socket fasteners are common. Typical applications include tightening set screws on motor shafts, fan hubs, valve stems, and equipment access panels. The gray handle provides visual identification in a tool pouch or kit. Sold individually, with a minimum order quantity of 10 units, making it practical for shop stocking or fleet-level tool distribution.

Compatibility

Designed as a standard long-arm hex key for use with inch-system hex socket fasteners across HVAC, plumbing, electrical, and general mechanical service applications.

Installation Notes

Insert the hex end fully into the fastener socket before applying torque to prevent rounding of the socket or key tip. Ensure the fastener and key size are matched before turning. When servicing powered equipment, de-energize and lock out the unit per applicable safety procedures before using hand tools on internal components. The long arm is intended for torque application; use the short arm for access in tight spaces if the key is reversible.
