Open-end box wrench 36 mm Kuźnia Sułkowice model 1-121-36-101

Combination wrench with an open-end and a box end for 36 mm fasteners, manufactured by Kuźnia Sułkowice (model 1-121-36-101). This single-piece hand tool is designed to apply torque to hexagonal nuts and bolt heads with a 36 mm size. Its compact, fixed-size design provides a direct mechanical connection between the user and the fastener, suitable for workshop, automotive and industrial applications where a dedicated 36 mm wrench is required.

Advantages

The wrench features a durable one-piece construction that ensures consistent torque transfer and reduced risk of deformation under load. The combination of an open-end and a box end gives flexibility when accessing fasteners in different positions: the open end allows quick placement and turning, while the box end provides a more secure grip for higher torque operations. Made from hardened steel with a finish resistant to corrosion and wear, it is built for repeated manual fastening and loosening tasks.

Suitable for

• Automotive maintenance and repairs involving 36 mm nuts and bolt heads
• Industrial machinery assembly and maintenance where a fixed-size 36 mm wrench is needed
• Workshop and garage use for routine tightening and loosening of large hex fasteners
• Situations requiring a compact, single-piece wrench for confined spaces or repetitive work

Key specifications

• Tool type: Combination wrench with open-end and box end
• Nominal size: 36 mm across flats
• Construction: Single-piece forged or machined steel
• Ends: One open-end jaw and one enclosed box end for secure engagement
• Surface: Protective finish to resist corrosion and wear
• Drive style: Manual hand-operated wrench for direct torque application

How to use

Position the open end over the nut or bolt head for quick turning or use the box end to fully enclose the fastener for higher torque and reduced slippage. Apply steady, controlled force to avoid sudden impacts; when maximum torque is required, ensure the wrench is fully seated on the fastener and pull with even pressure. For tight spaces, use the open end or reposition the wrench using the box end's indexing if available. Inspect the tool before use for signs of wear or damage and avoid using a damaged wrench.

Usage recommendations

Use the 36 mm combination wrench for its intended manual fastening tasks only. Avoid using cheater bars or extensions that exceed manufacturer-recommended leverage, as this increases the risk of tool failure and personal injury. Store the wrench in a dry place and keep it clean to prolong service life; periodically check for wear or rounding on the jaws before critical operations.
