  • Color and finishBlack Oxide
  • 14-piece set covers common fastener sizes

Professional Impact Socket Set

The Westward 4PRH5 provides fourteen 6-point standard sockets in a 1/2 inch drive size, covering a range from 7/16 inch to 1-1/4 inch. It is built for technicians and serious DIYers who need durable impact-rated tools for automotive and heavy fastening tasks. The black oxide finish resists corrosion during daily shop use. This set suits anyone requiring a complete range of common SAE sizes in one kit.

Hand Tool Operation

As a manual hand tool set, the 4PRH5 generates no operational noise, draws no power and produces no heat during normal use. Performance depends entirely on the impact wrench or breaker bar paired with the sockets. The black oxide coating helps maintain socket integrity under high torque loads. There are no thermal or acoustic characteristics to measure for the sockets themselves.

Organised Storage Included

The fourteen pieces are supplied in a fitted container that keeps every socket sorted and protected between jobs. This case prevents loss, speeds up size selection and shields the black oxide finish from shop contaminants. No additional software or digital accessories are included with this purely mechanical product. The storage solution is the only bundled extra.

Questions about this item

How do I attach the 1/2 in. drive sockets to my impact wrench without rounding the corners?

Match each 6-point socket to the fastener, seat it fully on the 1/2 in. drive anvil, and engage the impact wrench at low torque first; the black oxide finish helps grip but the 6-point profile does the real work of preventing corner rounding.

What upkeep does the black oxide coating on these 14 sockets require over time?

Wipe the sockets clean after each use, apply a light oil film before storage, and inspect the coating for wear; the black oxide resists corrosion but will thin with heavy impact cycles, so re-oiling keeps rust from starting.

At what point does the 6-point geometry become the limiting factor during continuous high-torque work?

Under sustained heavy impact the 6-point walls absorb the load until they deform; once the corners yield, the socket slips on the fastener, so stop and swap to a fresh socket when you feel rounding begin.
