Williams Comfort Products QYSD12A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYSD12A is a fixed square drive torque wrench head designed for precise fastener torque application in professional trade and mechanical service work. Built with a 3/8 inch drive and a Y-type shank measuring 0.560 inches, this head connects to compatible torque wrench handles to deliver controlled torque output up to 100 foot-pounds. It is sold individually and is suited for technicians who require repeatable, accurate torque application on fasteners in HVAC equipment, plumbing assemblies, and general mechanical systems. The SAE specification makes it compatible with standard inch-based fastener sets common across residential and light commercial service work.

This torque wrench head is appropriate for use in field service and shop environments where consistent fastener torque is required. HVAC technicians, plumbers, and mechanical contractors will find it useful when servicing equipment panels, compressor mounting hardware, and flanged connections that specify a torque value. Its compact form factor — approximately 3.8 inches in length — allows use in tighter service access areas compared to full-length torque wrenches.

Key Features

• 3/8 inch drive size for compatibility with standard torque wrench handles
• Fixed square drive head type for consistent, reliable engagement
• Y-type shank at 0.560 inches for secure handle attachment
• Rated up to 100 foot-pounds maximum torque output

Compatibility

Designed as an OEM-style torque wrench head for use with 3/8 inch drive torque wrench handles accepting a Y-type shank connection.

Installation Notes

Installation of this torque wrench head should be performed by a qualified technician familiar with fastener torque procedures. Ensure the wrench handle is de-energized or depressurized from any associated system before applying torque to fasteners. Verify the shank seating is secure before applying load to avoid slippage or inaccurate torque readings. Follow equipment manufacturer torque specifications and applicable codes such as IFGC or IPC where fastener torque is specified for pressure-bearing joints.
