Flat-ring wrench Dedra 29 mm model 14621

Flat-ring wrench Dedra 29 mm model 14621 is a hand tool designed for tightening and loosening hexagonal nuts and bolts with a 29 mm head. The tool combines an open (flat) end and a ring end in one piece, offering access to fasteners in tighter spaces as well as a secure, full-contact grip on the nut or bolt head. Constructed for general workshop, automotive and household use, this Dedra 29 mm spanner is suitable where a single, reliable 29 mm wrench is required.

Advantages

The combined flat and ring ends deliver both speed and security: the open end allows quick placement and turning in accessible positions while the ring end provides better torque transfer and reduced risk of rounding. The single-piece construction ensures alignment between the two ends and stable handling during use. The 29 mm size matches common larger fasteners found in automotive and maintenance tasks.

Suitable for

• Automotive maintenance and repair tasks requiring a 29 mm spanner
• Assembly and disassembly of machinery and equipment with 29 mm hex heads
• General workshop and garage tasks involving larger nuts and bolts
• Household repair tasks where a 29 mm flat or ring wrench is needed

Key specifications

• Wrench type: combined open-end and ring-end (flat-ring)
• Head size: 29 mm across flats
• Material: chrome-plated alloy steel (typical for hand tools of this class)
• Finish: polished or chrome-plated surface for corrosion resistance
• Drive style: 6- or 12-point ring profile depending on ring design
• Hand orientation: one-piece, fixed geometry with straight shank

How to use

Select the 29 mm end that best suits the access and torque requirements: use the open (flat) end for quick engagement and where the fastener is accessible from the side, and use the ring end for higher torque and to reduce slippage on tightened nuts or bolts. Place the wrench fully onto the nut or bolt head before applying force, and apply steady, controlled pressure while keeping your wrist aligned with the handle to avoid sudden slips. Inspect the tool and the fastener before use to ensure proper seating and to avoid rounding the corners of the fastener.

Usage recommendations

For prolonged service life and safer operation, store the wrench dry, clean it after use to remove grease and grit, and avoid using cheater bars or excessive impact force. For tasks requiring very high torque or where bolt condition is uncertain, consider using an appropriate torque tool or impact-rated equipment.
