Impact socket accessory Proline 18960, length 74 mm

Impact socket accessory Proline 18960, length 74 mm is an elongated hexagonal impact socket designed for use with impact wrenches and pneumatic or electric impact drivers. With a 74 mm overall length, this Proline accessory extends reach to recessed fasteners and provides the mechanical robustness needed for regular workshop and industrial tasks. Constructed from chromium-molybdenum (CrMo) steel, the socket is engineered for increased tensile strength and improved yield point compared with ordinary chromium-vanadium sockets, and it incorporates a rounded internal geometry to reduce stress on bolt edges during high-torque operations.

Advantages

The Proline 74 mm impact socket offers extended reach to access recessed or hard-to-reach fasteners while maintaining compatibility with common square drives and locking mechanisms used on pneumatic devices. The CrMo steel construction delivers higher tensile strength and improved fatigue resistance, and the PRO-DRIVE rounded internal corners reduce concentrated point loads on fastener heads, increasing socket life and protecting bolt edges during repeated impact use. The socket is suitable for demanding working conditions and fluctuating loads.

Suitable for

• Automotive service and repair where bolts are recessed or in hard-to-reach locations
• Mechanical and industrial maintenance requiring higher-strength impact sockets
• Workshops using pneumatic impact wrenches or electric impact drivers
• Applications where extended socket length is necessary to clear surrounding parts

Key specifications

• Type: elongated hexagonal impact socket
• Length: 74 mm overall reach
• Material: chromium-molybdenum (CrMo) steel for enhanced strength
• Internal geometry: rounded work plane corners (PRO-DRIVE) to reduce point loading
• Drive interface: square drive compatible with common locking mechanisms
• Usage: designed for use with pneumatic and electric impact tools

How to use

Select the correct socket size for the fastener and attach the socket securely to a compatible square drive impact wrench or driver. Ensure the socket engages fully with the fastener head and that any locking mechanism is properly seated. Use the impact tool according to the tool manufacturer’s operating instructions and apply controlled bursts of torque as required. After use, inspect the socket and fastener for wear or damage and store the socket in a dry, clean environment to prevent corrosion.

Usage recommendations

Use with impact-rated extensions or adapters when additional reach is required, avoid using the socket with hand-only ratchets or non-impact tools, and replace the socket if visible cracking, rounding, or excessive wear appears. Regularly clean and lightly lubricate the drive interface to maintain secure attachment and prolong service life.
