Impact socket accessory Proline ZR18928, length 53 mm

Proline ZR18928 is an impact socket accessory with a 53 mm overall length designed for use with impact wrenches and pneumatic or electric fastening tools. Made from chromium-molybdenum (CrMo) steel, this hexagonal impact socket is intended for demanding working conditions where high torsional loads and repeated impacts occur. The socket features rounded internal angles (PRO-DRIVE system) to reduce point loading on fastener edges and improve torque transfer and component life.

Advantages

The chromium-molybdenum construction provides elevated tensile strength and yield point compared with conventional chromium-vanadium sockets, resulting in longer service life under impact use. The PRO-DRIVE rounded profile reduces stress concentrations on bolt heads and socket walls, allowing higher torque application while lowering the risk of cracking. The square drive end is compatible with common locking mechanisms on pneumatic and electric impact tools. Its 53 mm length offers access to slightly recessed fasteners without sacrificing strength.

Suitable for

• Automotive repair and wheel and suspension work
• Industrial maintenance and machine assembly
• Pneumatic and electric impact wrench applications
• Tightening and loosening hex fasteners under heavy load

Key specifications

• Type: Hexagonal impact socket
• Material: Chromium-molybdenum (CrMo) steel
• Length: 53 mm
• Drive style: Square drive compatible with standard locking mechanisms
• Internal profile: PRO-DRIVE rounded angle design
• Finish: Impact-rated industrial finish suitable for heavy-duty use

How to use

Select the correct socket size for the fastener and attach it securely to the impact wrench’s square drive, ensuring the locking mechanism engages. Position the socket over the fastener and operate the impact tool according to the tool manufacturer’s instructions, applying controlled bursts of torque as required. After use, inspect the socket for deformation or cracking and store in a dry, organized location to prevent corrosion and damage.

Usage recommendations

Use with properly rated impact tools and appropriate personal protective equipment. Avoid using the socket with hand tools or for chiseling; do not apply heat treatments or modify the socket. Replace the socket if significant wear, rounding, or cracking is visible to maintain safe torque transfer and prevent fastener damage.
