1/2-Inch Drive Spline Impact Socket, Tamper Profile, M18

Brief Overview

This 1/2-inch drive spline impact socket is engineered for professionals who need reliable, non-slip engagement with spline-drive fasteners. The multi-lobed tamper profile prevents fastener rounding and cam-out—critical for stubborn or damaged fasteners in automotive and industrial maintenance work. Built from impact-grade chrome-molybdenum steel with a dark oxide finish, it's designed to withstand the shock loads of pneumatic and electric impact tools. Whether you're stocking professional garages or selling to independent technicians, this socket delivers the precision fit that keeps jobs moving. Complement this with standard hex impact sockets or comprehensive impact socket sets to round out your 1/2-inch drive offerings.

Key Features

• Spline/Tamper Profile: Multi-lobed recess designed for positive engagement with spline-drive fasteners; resists rounding and cam-out on difficult fasteners
• Chrome-Molybdenum Construction: Impact-grade alloy delivers toughness under shock load without brittleness
• Dark Oxide Finish: Corrosion-resistant coating protects against rust and extends tool life in humid shop environments
• Retaining Pin Slot: Integrated collar slot accommodates standard 1/2-inch drive retention clips for secure tool attachment
• Precision Machining: Lobes are precisely machined to ensure consistent, tight fit with spline fasteners
• M18 Size: Fits M18 spline-drive fasteners (common in European automotive and industrial applications)

Why This Socket Matters for Your Business

For Resellers:

• High Demand Category: Spline-drive fasteners are increasingly common in modern automotive assemblies; shops that lack proper spline sockets create service callbacks and customer dissatisfaction
• Margin Opportunity: Spline sockets command higher price points than standard hex sockets due to their specialized profile
• Repeat Orders: Professionals who discover they need spline sockets typically buy multiple sizes at once—bundle this with M14, M16, and M20 sizes for stronger orders

For End Users (Your Customers):

• Prevents Fastener Damage: Spline engagement eliminates the rounding that hex sockets can cause on delicate or damaged fasteners
• Time Savings: Proper fit means first-time success; no slipping, no stripped fasteners, no comebacks
• Durability: Chrome-molybdenum impact rating means this socket handles pneumatic impact tool abuse without cracking or deforming
