Proto J6177F Dial Torque Wrench 3/8 in Drive 250 In/lb

Product Description

The PROTO J6177F is a dial torque wrench designed for precise fastener torque measurement in mechanical and service applications. Built around a 3/8 inch drive, it reads torque in inch-pounds via an analog dial face, giving technicians a direct, real-time readout without clicking or digital display complexity. The wrench covers a range of 0 to 250 in/lb with a graduation resolution of 5 in/lb, making it suitable for applications where controlled torque is critical and repeatability matters. With a fixed head and a 10 inch overall length, it fits into tight access areas while still delivering meaningful torque capacity. Licensed trades and service technicians in HVAC, plumbing, and general mechanical work rely on dial torque wrenches when fastener specs must be documented or verified.

The J6177F is used in residential and light commercial service environments wherever fasteners require torqued-to-spec assembly or inspection. Typical applications include equipment panels, access covers, compressor service, pump assemblies, and any mechanical connection where over-torquing would damage threads or under-torquing would compromise the joint. The 3/8 inch drive accepts standard sockets, making it compatible with a wide range of socket sets already common in service vans and shop tool kits.

Key Features

• Dial display provides continuous torque readout from 0 to 250 in/lb
• 3/8 inch drive accepts standard socket accessories
• 5 in/lb graduation increments for precise fastener torque control
• Fixed head design for consistent angle and reliable dial readings
• Compact 10 inch overall length suits confined service spaces
• Weighs 1.96 pounds for comfortable single-hand use during extended service work

Compatibility

Designed as an OEM-style professional torque wrench compatible with any 3/8 inch drive socket set used in mechanical, HVAC, plumbing, and general trade service applications.

Installation Notes

Dial torque wrenches are typically used by licensed mechanics, HVAC technicians, and plumbers during assembly or inspection of torque-critical fasteners. Always power down and de-energize equipment before accessing fastener assemblies on live systems. Apply torque smoothly and read the dial at eye level to avoid parallax error. Do not use extension bars unless the torque specification accounts for the added flex, and do not store the wrench under load.
