A compact, impact-ready hand tool for scaffold work, SCAFFPRO Scaffolding Impact Socket promises secure fastening on site. Professional scaffolders and contractors gain confidence from a deep, robust design that locks to an impact wrench. Are the secure O-ring attachment and six-sided fitment enough to justify a place in a daily toolkit?
⚡ At a Glance
- • Grip & Fitment: 6-sided engagement ensures precise contact with fastener flats to reduce rounding
- • Best for: Professional scaffolders and tradespeople needing a deep, impact-rated 21mm socket
- • Not ideal for: Users requiring a set of multiple socket sizes or shallow, low-profile sockets
Deep 21mm impact socket made from chrome molybdenum steel with a 52mm overall length. O-ring and retainer pin secure attachment to a 1/2 inch drive impact wrench.
Secure Attachment – Thanks to O-ring and retainer pin
An O-ring together with a retainer pin locks onto a 1/2 inch drive, preventing separation under impact torque. The retention method resists knocks and sudden movement common on site.
Secure on-wrench retention reduces the chance of dropped sockets when working overhead or in awkward positions, keeping jobs moving and avoiding lost parts.
Access Tight or Recessed Fasteners – With a 52mm deep design
A 52mm overall length places hex engagement deeper on studs and recessed nuts, while the deep profile maintains clearance for surrounding scaffold components. The design balances reach with a compact form factor for close quarters.
Makes it simpler to reach nuts on longer studs or inside cage-like scaffold sections, saving time compared with standard shallow sockets.
Less Fastener Damage – With 6-sided fitment and chrome molybdenum steel
Six-point hex engagement distributes torque across flat faces of a fastener rather than corners, and chrome molybdenum construction resists deformation under repeated impact.
Reduced risk of rounding bolts and a durable head that stands up to heavy on-site use, so fasteners remain serviceable longer.

Q: What are the size and reach of the socket?
A: A 21mm hex size with a 52mm overall length offers extra reach for recessed fasteners and studs.
Q: Will the fitment reduce rounding of fasteners?
A: Yes, the 6-sided fitment engages fastener flats precisely to lower the chance of rounding under torque.
🏆 Our Verdict
Ideal for professional scaffolders who need a single, robust 21mm impact socket for on-site work. Secure retention with an O-ring and pin, a 52mm deep profile, and six-sided fitment make it particularly well suited to recessed and repetitive fastening tasks. While an investment in a specialist tool, durable chrome molybdenum construction suggests long-term value for daily use.
