Hand tool for fastening and loosening bolts with a promise of precise control in confined spaces. Save time and avoid awkward repositioning when working around pipework or in engine bays with Silverline Flexible Head Ratchet Spanner. Is this the right 17 mm spanner for regular DIY and trade work?
⚡ At a Glance
- • Ratchet Action: 5° ratchet action for fine incremental turns
- • Best for: DIYers and tradespeople needing precise access in tight spaces
- • Not ideal for: Heavy industrial applications that require power tools or very high torque
Five-degree ratchet increments enable careful tightening or loosening. Compact head profile helps reach bolts in confined areas.
Work in confined spaces – with a 180° pivoting head
A head that pivots through 180° allows the wrench to change angle relative to the handle, enabling engagement of fasteners from awkward approaches. The pivot mechanism keeps the jaw aligned while the handle clears surrounding obstructions.
Access bolts behind brackets, inside engine bays or between pipe runs without continually repositioning the whole tool. Saves time and reduces strain when working in cramped locations.
Precise turning control – thanks to 5° ratchet action
A 5° tooth spacing in the ratchet mechanism permits small, incremental rotations before the jaw re-engages. Finer tooth engagement reduces the required handle swing for each click.
Tightening or loosening fasteners in narrow spaces becomes more manageable because small handle movements achieve measurable rotation. Less effort is needed where clearance is limited.
Long service life – with hardened, tempered chrome vanadium construction
Hardened and tempered chrome vanadium steel increases tensile strength and resistance to deformation under torque. The alloy tolerates repeated stress cycles better than standard mild steels.
Expect the wrench to retain shape and function under routine workshop demands, giving reliable performance over extended use. Dependable construction reduces the likelihood of rounding fasteners.
✨ The 4 Key Reasons for Silverline Flexible Head Ratchet Spanner
- Hardened Chrome Vanadium – Retains shape under high torque for extended service life
- Chrome Plating – Prevents corrosion for reliable use in humid or workshop conditions
- Mirror-Polished Finish – Smooth surface sheds grease and simplifies cleaning after jobs
- 180° Pivoting Head – Allows awkward-angle access without moving the handle in tight spots
