2616PM-Spline Socket Wrench Set- ¼” Drive-16PCs

Universal Spline Geometry & Military-Spec Design

The high-performance engineering of the 24P0M socket line features advanced contact profiles optimized for complex mechanical systems:

• Military Standard MS-33787 & MIL-W-8982 Compliance: The internal socket configuration is manufactured to strict military and aerospace structural standards. The unique wave-profile spline pattern enables the interior load points to adapt perfectly to 6-point, 12-point, square, spline, XZN, and E-Star hardware, reducing the total tool inventory required on site.
• Flank-Drive Stress Distribution: Unlike budget 6-point sockets that press directly on the fragile corners of a nut, the spline architecture channels rotational force to the flat sides (flanks) of the fastener. This protects rusted or soft-alloy hardware from stripping or rounding out under high breakaway torque loads.
• Premium Vanadium Metallurgy: Cold-forged from high-grade Chrome Vanadium (Cr-V) steel, the components undergo uniform vacuum through-hardening to achieve high fatigue resistance. A mirror-polished chrome layer shields the tools from rust and shop chemicals.

1/4″ Drive Interface Architecture & Specialized Accessories

• High-Precision 凹 (Concave/Female) & 凸 (Convex/Male) Matching: Every hand socket features a precision-broached internal 凹 (concave/female) square pocket with an active ball-detent recess. This creates a secure, wiggle-free interlocking fit onto the 1/4″ 凸 (convex/male) anvil of the included 2100PQ quick-release ratchet, extension bar, spinner handle, or sliding T-bar.
• 2100PQ Quick-Release Ratchet Core: The kit includes the iconic 5″ (130mm) HANS quick-release ratchet handle. Equipped with a fine-tooth internal gear assembly and a top-mounted push-button detent pin release, it enables technicians to pop sockets off instantly—even when working with greasy hands in tight spaces.
