Impact socket accessory Proline ZR18428, length 48 mm

Proline ZR18428 is an impact socket accessory with a 48 mm length designed for use with impact wrenches and pneumatic or electric impact drivers. Made for demanding workshop and professional environments, this Proline hexagonal impact socket is manufactured from chromium-molybdenum (CrMo) steel to provide higher tensile strength and improved wear resistance compared with standard chromium-vanadium sockets. The socket features the PRO-DRIVE rounded internal angle profile to reduce point loading on fastener corners and extend both the socket and fastener life. The square drive is compatible with common locking mechanisms used on pneumatic impact tools and the construction is suitable for repeated impact loading.

Advantages

The CrMo steel construction delivers increased tensile strength and a higher yield point, improving durability under heavy loads. The PRO-DRIVE internal profile lowers stress concentrations on bolt heads and prevents premature rounding, allowing greater torque transfer without socket wall failure. Compatibility with standard square drive locking systems ensures secure attachment to most impact wrenches and drivers. The 48 mm length provides extra reach for recessed or hard-to-access fasteners while retaining impact-rated toughness for frequent use.

Suitable for

• Fastening and loosening hex nuts and bolts in automotive repair and maintenance
• Assembly and disassembly work in mechanical workshops and maintenance shops
• Use with pneumatic or electric impact wrenches in construction and industrial settings
• Tasks requiring extended reach to access recessed or obstructed fasteners

Key specifications

• Socket type: hexagonal impact socket
• Length: 48 mm
• Material: chromium-molybdenum (CrMo) steel
• Internal profile: rounded angles (PRO-DRIVE) to reduce point loading
• Drive interface: square drive compatible with standard locking mechanisms
• Designed for use with pneumatic and electric impact tools

How to use

Select the correct socket size for the fastener and attach the socket to the impact wrench's square drive until the locking mechanism engages. Position the socket over the nut or bolt head, ensure proper seating on the fastener, and apply controlled bursts of torque with the impact tool. For removal, use the same procedure in reverse direction. After use, inspect the socket for cracks or deformations and store in a suitable toolbox or rack to prevent damage.

Usage recommendations

Use only with impact-rated tools; do not use with hand ratchets or non-impact drivers. Wear appropriate eye and hand protection when operating impact tools. Replace sockets that show visible cracks, rounding, or deformations to maintain safe operation and reliable torque transfer.
