1/4 Inch Drive x 4 mm Deep 12-Point Impact Socket

• Two Size Markings – The size is marked in two ways, both as a high-visibility laser marking and a permanent stamped marking • Full-Length Socket Well – The interior well extends fully into the socket, which allows for better fastener engagement in more situations • Works With Friction Ring or Detent Pin Anvils – Smooth walls inside the drive end and a detent pin hole make the sockets compatible with both drive tool anvil types • Prevents Fastener Round-Off – Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners • High-Performing Steel Alloys – This socket is made from 50BV30 Chromium-Vanadium (Cr-V) and has a corrosion-resistant manganese phosphate coating
Tekton deep impact sockets have two size markings—both a high-visibility laser marking and a permanent stamped marking. The interior well of the socket extends fully into the socket, which allows for better fastener engagement in more situations. Each socket works with both friction ring and detent pin anvils. Smooth walls without grooves support friction ring engagement, and a detent pin hole on one side allows you to decide whether to engage the pin. Radiused corners on the socket prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners. Part by part, we choose the best combination of steel alloys, heat treating specifications, and forming processes to meet the highest performance requirements. This socket has a corrosion-resistant manganese phosphate coating.
