Paramount PAR37270 Hex Key 7.00mm Short Arm

Product Description

The PARAMOUNT PAR37270 is a metric short-arm hex key designed for driving 7.00 mm hex fasteners in confined or torque-critical applications. Built from Protanium High Torque Steel, this key delivers greater torsional strength than standard chrome-vanadium alternatives, reducing the risk of rounding fastener sockets under heavy load. The short-arm configuration keeps the overall length to 3-45/64 inches, making it practical in tight spaces where a long-arm key cannot swing freely. Licensed tradespeople and maintenance professionals working on mechanical assemblies, equipment panels, and fixtures will find it suited to repetitive service tasks requiring consistent torque delivery.

This hex key is used in industrial maintenance, mechanical service, and trade applications where metric fasteners are standard. The short-arm style is common in HVAC equipment access panels, pump and motor assemblies, and plumbing fixture installations where fastener recesses limit tool clearance. The gray handle finish and Protanium steel construction make it identifiable and durable in a working tool pouch. It is sold individually per package, with a minimum order quantity of 5 units.

Key Features

• Protanium High Torque Steel construction provides higher torsional strength than standard hex key alloys
• 7.00 mm metric hex size for compatibility with common metric socket-head fasteners
• Short-arm style at 3-45/64 inches overall length suits restricted-access fastener locations
• Hex end tip engages fasteners securely and resists cam-out under load
• Gray handle color aids quick identification in a tool kit or service bag

Compatibility

Designed as a standard metric short-arm hex key for use with 7.00 mm hex socket-head fasteners across mechanical, HVAC, plumbing, and general trade service applications.

Installation Notes

Insert the hex tip fully into the fastener socket before applying torque to avoid rounding the drive recess. Confirm the fastener hex size matches 7.00 mm before use, as metric and fractional-inch hex sizes can appear similar but are not interchangeable. Power down or de-energize any equipment before accessing panels or assemblies secured by these fasteners. No special certifications are required to use hand tools, but always follow applicable safety codes for the trade task being performed.
