PROTO is a professional hand tool brand with a history dating to the early 20th century, recognized for tools used in industrial maintenance, assembly, and heavy-duty mechanical work. The line includes torque wrenches, ratcheting wrenches, pipe wrenches, screwdrivers, and tool storage. 3G Electric supplies PROTO tools globally to plant engineers, maintenance managers, and procurement specialists who require documented torque control and durable hand tools for production and service environments.
PROTO torque wrenches cover micrometer, dial, and electronic types. Micrometer models include the J6014CXCERT with a 1/2 in square drive and 50–250 ft-lb range, and the J6016CXCERT with a 1/2 in drive and 30–150 ft-lb range; both are tether capable for drop prevention. The J6113F dial torque wrench has a 3/8 in drive, 10–50 ft-lb (1–7 m-kg) range, a memory needle, and an overall length of 10 1/4 in. The J6345A electronic torque wrench provides 5–50 ft-lb control with audible and visual indicators and supports Newton-Meter units. These tools are used where fasteners must be tightened to specified values and where traceability of applied torque matters.
Ratcheting combination wrenches are available in sets such as the JSCVM-20SB, a 20-piece metric 12-point set ranging from 6 mm to 32 mm, made from alloy steel with a chrome finish and supplied in a tool roll. For pipe and fitting work, the J812HD straight pipe wrench has a 12 in overall length, 2 in jaw capacity, serrated jaws, an I-beam handle, and cast iron construction. The J61929 multi-bit screw and nut driver kit contains 28 pieces, including 26 alloy steel bits with single-end tips in Phillips sizes #0 through #3, intended for precision fastening in assembly and maintenance tasks.
Tool storage and organization include the JUC3743-3SG heavy-duty utility cart, measuring 37 in wide by 20 in deep by 43 in high, with a gray body, red drawers, a hinge, a power strip, and a padlock. This cart supports keeping tools and fasteners organized at the point of use.
3G Electric supports the PROTO line by providing global availability, product specifications, and quotation support for procurement and maintenance teams. The catalog includes drive sizes, torque ranges, overall lengths, jaw capacities, and piece counts to assist with selection. For buyers specifying torque tools, the range of mechanical and electronic options allows matching the instrument to the required torque value and documentation needs. 3G Electric ships worldwide and can source PROTO tools for industrial, energy, and manufacturing applications.

Frequently asked questions
Common questions about PROTO from 3G Electric.
What is the difference between the PROTO J6014CXCERT and J6016CXCERT micrometer torque wrenches?
Both are ratcheting micrometer torque wrenches with a 1/2 in square drive and tether capability for drop prevention. The J6014CXCERT covers 50–250 ft-lb, while the J6016CXCERT covers 30–150 ft-lb. The choice depends on the target torque values: the J6016CXCERT is suited to lower-range fasteners, and the J6014CXCERT to higher-range applications. Both are used for precise tightening where a specified torque must be applied.
Does the PROTO J6113F dial torque wrench have a memory needle?
Yes. The J6113F is a standard-head dial torque wrench with a 3/8 in drive, a torque range of 10–50 ft-lb (1–7 m-kg), and an overall length of 10 1/4 in. It includes a memory needle that captures peak torque during tightening, which is useful when the operator cannot observe the dial continuously. This model is used for applications requiring visual confirmation of applied torque.
What is the torque range and drive size of the PROTO J6345A electronic torque wrench?
The J6345A is a standard-head, high-accuracy electronic torque wrench with a range of 5–50 ft-lb and an overall length of 11 in. It provides audible and visual indicators and supports Newton-Meter units. It is used where precise torque control and clear feedback are needed, such as in assembly or maintenance tasks with specified torque values.
What sizes are included in the PROTO JSCVM-20SB ratcheting combination wrench set?
The JSCVM-20SB is a 20-piece metric 12-point ratcheting combination wrench set ranging from 6 mm to 32 mm. The wrenches are made from alloy steel with a chrome finish and are supplied in a tool roll. This set covers a broad range of metric fastener sizes for maintenance and assembly work.
What are the dimensions and features of the PROTO JUC3743-3SG utility cart?
The JUC3743-3SG is a heavy-duty utility cart measuring 37 in wide, 20 in deep, and 43 in high. It has a gray body with red drawers, a hinge, a power strip, and a padlock. It is used for organizing and transporting tools and fasteners in industrial settings. The power strip allows for on-cart power access, and the padlock provides a locking option.
What is the jaw capacity of the PROTO J812HD straight pipe wrench?
The J812HD is a 12 in straight pipe wrench with a 2 in jaw capacity. It has serrated jaws and an I-beam handle, and is made of cast iron. It is designed for gripping and turning pipes and fittings in plumbing and mechanical applications. The serrated jaws are intended to provide grip on pipe surfaces.
