A home improvement impact socket designed to reach deep scaffold clamps and stubborn long bolts, with corrosion-resistant CR-V construction. That reassurance helps tradespeople and DIYers, with the Onperpoe 21mm Scaffolding Impact Socket, remove rusted fasteners without constant slippage. Does the secure fit and specialist design belong in every toolkit?
⚡ At a Glance
- • Drive Strength: Chrome vanadium construction tolerates heavy torque and resists rounding
- • Best for: Tradespeople and DIYers working on scaffolding, fencing and exhausts
- • Not ideal for: Fine mechanical work requiring very shallow sockets
Deep 34mm inner depth reaches long-threaded bolts and recessed fasteners. Hexagonal head design and CR-V steel reduce slipping while a protective coating extends service life.
Reach recessed fasteners - thanks to 34mm inner depth
A 34mm inner depth allows the socket to slide over long threads and reach nuts set well below the fastener head. The long socket form handles stubborn or rusted bolts that shallow sockets cannot access.
Access recessed scaffold clamps and long bolts without removing surrounding hardware. Faster removal of deep fasteners saves time on site and in the workshop.
Resists heavy torque - with CR-V chrome vanadium steel
Chrome vanadium (CR-V) construction offers high tensile strength and resilience under impact. The material tolerates the strong torque produced by impact drivers and heavy-duty ratchets.
Sustained use on tough fasteners does not deform the drive or rounding the fastener faces. Dependable longevity reduces the need for frequent replacements.
Secure grip under load - with hexagonal head design and retaining system
Hexagonal geometry grips flat surfaces of fasteners to limit slippage and edge rounding under torque. A retaining pin and O-ring keep the socket fixed to the drive during heavy or overhead work.
Safer, more controlled loosening and tightening on scaffolding and fencing jobs. Reduced risk of accidental disconnection gives confidence when working at height.
