Hand tool for scaffolding and heavy maintenance that promises secure removal of deep-set bolts and long fasteners. Othmro Scaffolding Impact Socket helps tradespeople work confidently when access is awkward or bolts sit recessed. Is the heavy-duty build the right choice for regular impact use on site?
⚡ At a Glance
- • Grip and Fit: Snug engagement with 21mm nuts, designed to sit firmly on a 1/2-inch square drive for stable operation
- • Best for: Tradespeople and DIYers removing deep-set scaffolding bolts, long fasteners and exhaust system nuts
- • Not ideal for: Use with drives smaller than 1/2-inch or for delicate non-impact hand-tightening tasks
21mm deep impact socket with extended inner depth and 78mm overall length, compatible with 1/2-inch square drive impact tools. Cr-Mo Chrome Vanadium steel and a phosphide black finish add wear and corrosion resistance.
Secure grip under torque - with a hexagonal drive head
Hexagonal inner profile contacts the flat faces of nuts rather than corners, spreading force across a larger area and lowering the risk of slip under high torque. Specially shaped impact head reduces edge rounding when using high-power wrenches.
Firmer engagement lets fasteners break free more predictably, reducing damage to bolt heads and speeding up removal on scaffolding clamp work.
Durability for repeated impact - with Cr-Mo Chrome Vanadium construction
Manufactured from Cr-Mo Chrome Vanadium steel, the alloy resists deformation and cracking under repeated impact loads. A phosphide black finish increases surface wear resistance and helps guard against rust.
Robust construction means fewer failures during heavy site use and a longer working life compared with standard sockets.
Access to recessed fasteners - with extended inner depth and retaining hardware
78mm length and deep inner profile reach long bolts and recessed nuts commonly found on scaffolding and exhaust systems. Included retaining pin and O-ring lock the socket to a 1/2-inch square drive to prevent accidental disconnection during overhead work.
Safer, more reliable overhead and hard-to-reach jobs, with reduced risk of the socket falling off when working at height.
✨ The 4 Key Reasons for Othmro Scaffolding Impact Socket
- Extended Reach - Reaches recessed nuts on scaffolding and exhaust systems
- Impact-grade Cr-Mo Chrome Vanadium - Withstands repeated high-torque impact use
- Hexagonal Drive Head - Reduces slippage and rounding of fastener edges
- Retaining Pin and O-ring - Locks socket to drive, preventing accidental disconnection
