Impact Hex Socket 1/2" 16 mm long — NEO tools 12-316

Long 16 mm hex impact socket with a 1/2" drive from NEO tools, model 12-316, is engineered for heavy-duty fastening tasks where access and durability are required. The extended profile reaches recessed hex fasteners on engines, gearboxes and machinery, while the design is optimised for use with impact wrenches and pneumatic or electric drivers. Hardened steel construction and an impact-rated finish provide resistance to deformation under high torque and repeated impacts.

Advantages

The long 16 mm hex impact socket offers improved reach to deep or recessed bolts compared with standard-length sockets, reducing the need for extensions. Its 1/2" drive interface ensures compatibility with common impact wrenches and breakers. Heat-treated steel and a wear-resistant surface finish increase lifespan under frequent use in automotive and industrial environments. The long profile also improves clearance around obstacles, enabling safer and more efficient fastening operations.

Suitable for

• Removing and tightening recessed hex bolts on automotive engines and transmissions
• Maintenance and repair of industrial machinery and production equipment
• Assembly work where deep-set fasteners require extended reach
• Use with impact wrenches, pneumatic drivers and heavy-duty ratchets

Key specifications

• Hex size: 16 mm
• Drive size: 1/2" (square drive)
• Type: long impact socket (extended profile)
• Material: hardened impact-grade steel with protective finish
• Intended use: compatible with impact tools and high-torque applications

How to use

Select the 16 mm hex impact socket and securely attach it to a 1/2" impact wrench or driver. Ensure the socket is fully engaged on the fastener before applying torque. When loosening, use short bursts of the impact tool and maintain a firm grip to control reaction forces. After use, inspect the socket for cracks or deformation and clean any debris or grease before storage to maintain safe operation.

Usage recommendations

Use the socket only with impact-rated tools and accessories. Avoid using cheater bars or hand extensions on the tool while the impact wrench is running. Replace the socket if any visible damage or rounding of the hex profile occurs to prevent fastener damage and ensure operator safety.
