Key Functions
Full-Length Socket Well
The interior well extends fully into the socket, allowing better fastener engagement in more situations—gripping nuts on long studs where shallow sockets bottom out.
Prevents Fastener Round-Off
Radiused corners apply force to the fastener's flat sides rather than its corners, protecting 18 mm nuts and bolts from damage during impact driving.
Works with Both Anvil Types
Smooth walls support friction ring engagement, and a detent pin hole lets you choose pin retention when needed.
Compatibility
Fits all 3/8 in. drive impact wrenches, impact drivers, breaker bars, and ratchets with friction ring or detent pin anvils. Ideal for automotive suspension, exhaust, and general mechanical work on 18 mm metric fasteners.
How It Compares
Shallow sockets can't grip nuts on extended studs; deep sockets add unwanted length. The semi-deep design is the problem-solving middle ground. Compared to generic sockets, TEKTON's dual markings and Cr-V alloy deliver lasting, identifiable performance at a $5.50 price point.
