Wiha 28501 Torque Limiting Screwdriver Adjustable

Product Description

The WIHA 28501 is an adjustable torque limiting screwdriver designed for precision fastening applications where consistent torque output is critical. The tool operates within a range of 15 to 80 inch-ounces, allowing technicians to dial in the exact torque setting required without risk of over-tightening sensitive fasteners. With an overall length of 5 inches and a 1/2-inch drive, it fits comfortably in hand for close-quarters work. Rated for a minimum of 5,000 cycles, the 28501 is built for repeated daily use in field and bench applications. Electricians, HVAC technicians, and electronics assemblers rely on this type of tool when working with delicate terminals, panels, or equipment enclosures.

This screwdriver is suited for light assembly and service tasks where fastener torque must stay within a controlled range to protect components. Typical applications include tightening terminal screws on control boards, panel components, and instrument enclosures. The adjustable range of 15 to 80 inch-ounces covers a wide variety of small-fastener scenarios found in both residential and light commercial service work. The compact 5-inch overall length makes it practical in tight spaces and equipment cabinets.

Installation Notes

This tool is used by electricians, HVAC technicians, and assembly technicians for controlled fastener tightening. Always power down and de-energize equipment before working on terminals or enclosures, in accordance with NFPA 70E lockout/tagout procedures. Set the torque adjustment to the required value before applying the driver to the fastener. Do not exceed the rated maximum torque of 80 inch-ounces, as this may damage the internal limiting mechanism.
