Flat Wrench Forsage F-7542123 21x23 mm, Length 245 mm, Cr-V

Forsage flat wrench F-7542123 combines two common metric jaw sizes — 21 mm and 23 mm — in a single fixed open-end tool. The wrench is 245 mm long and manufactured from chromium-vanadium (Cr-V) steel, providing the rigidity and wear resistance required for routine tightening and loosening of hexagonal nuts and bolts. Its straight, slim profile is intended for work in workshops, garages and field-service situations where access and leverage are important.

Advantages

The Cr-V construction offers enhanced hardness and resistance to deformation under torque while maintaining reasonable toughness to reduce breakage risk. Two-size open ends save time and space by replacing two separate wrenches. At 245 mm length the tool delivers a balance between reach and torque, allowing improved access to recessed fasteners and sufficient leverage for common automotive and mechanical tasks. The flat profile helps access narrow spaces where bulkier adjustable tools would not fit.

Suitable for

• Automotive maintenance and repair jobs involving 21 mm and 23 mm fasteners
• Mechanical assembly and disassembly of machines and equipment
• General workshop and garage use for tightening and loosening hex bolts
• Field service and maintenance where a compact, two-size wrench is useful

Key specifications

• Jaw sizes: 21 mm and 23 mm
• Overall length: 245 mm
• Material: chromium-vanadium (Cr-V) steel
• Type: open-end (flat) wrench with two fixed jaws
• Finish: machined metal surface suitable for workshop use

How to use

Select the jaw size that matches the nut or bolt head and position the open end fully over the fastener to avoid slippage. Apply steady force to the handle while keeping the wrench aligned with the fastener axis; use controlled, gradual pressure to tighten or loosen. For higher torque requirements, ensure contact is secure and re-seat the wrench between turns. Avoid using excessive impact or hammering on the flat wrench to prevent tool or fastener damage.

Usage recommendations

Store the wrench in a tool rack or toolbox to prevent corrosion and mechanical damage. Clean and lightly oil the tool after exposure to moisture or corrosive environments. When working on critical or rusted fasteners, consider using appropriate penetrating lubricant and the correct-size wrench to reduce rounding of bolt heads.
