Open End Wrench HAZET 450N-17X19

The HAZET 450N-17X19 open end wrench is a single-piece hand tool designed for turning fasteners with 17 mm and 19 mm widths across flats. Manufactured from chromium-vanadium steel, it combines torsional strength with surface durability. With a length of 220.9 mm and a mass of approximately 136 g, the wrench offers extended reach and mechanical advantage while remaining light enough for repetitive use in workshop and field environments.

Advantages

The one-piece construction reduces the risk of joint failure and delivers consistent force transfer to the jaws. Chromium-vanadium steel provides high tensile strength and resistance to wear, while the polished finish aids in corrosion resistance and simplifies cleaning. The 17x19 mm double-ended design enables quick switching between two common metric sizes without changing tools, improving workflow efficiency.

Suitable for

• Tightening and loosening hex-head nuts and bolts in automotive repair
• Assembly and maintenance of mechanical and industrial equipment
• Household and DIY projects requiring metric wrench sizes
• Field service work where a compact, lightweight wrench is preferred

Key specifications

• Material: chromium-vanadium steel
• Sizes: 17 mm and 19 mm open ends
• Overall length: 220.9 mm
• Weight: approx. 136 g
• Design: double-ended open wrench, single-piece construction
• Finish: polished surface for improved corrosion resistance

How to use

Select the end that matches the fastener size, place the open jaw fully onto the nut or bolt head, and apply steady force to turn. Use the longer handle for additional leverage on stubborn fasteners while taking care not to exceed the mechanical limits of the fastener or wrench. For recurring tasks, ensure proper hand positioning to maintain control and avoid slipping; if more torque is required, consider using an appropriately sized socket or torque wrench to prevent rounding the fastener.

Usage recommendations

Regularly inspect the jaw faces for wear and keep the wrench clean and lightly oiled to protect the chromium-vanadium surface. Avoid using the wrench as a hammer or pry bar. Store in a tool rack or toolbox to prevent damage and maintain accurate fit on fasteners.
