Stainless Steel L-Handle Push Button Locking Pin | SNBLP000009 | Sinoboltco

The Sinoboltco SNBLP000009 L-Handle Quick Release Ball Lock Pin is an engineered fastening solution designed for high-frequency connection and alignment tasks in modern industrial environments. Built for speed, precision, and repeatability, this fastener allows operators to perform tool-free assemblies and fast equipment changeovers.

Engineered Material Selection

To withstand harsh industrial conditions and corrosive environments, the core components—including the pin shaft, internal tension spring, actuation push button, locking balls, and retaining ring—are manufactured entirely from premium stainless steel. The ergonomic L-shaped handle is crafted from lightweight, durable aluminum alloy, providing high structural strength without adding unnecessary weight to dynamic assembly setups.

Operational Mechanism & Positive Locking

Pressing the blue top actuation button compresses the internal spring and retracts the dual stainless steel locking balls flush into the shank diameter (ΦA).

Slide the pin into the reamed mounting hole of your jig or fixture.

Releasing the button forces the locking balls outward beyond the shank diameter (Dimension B), creating a secure, positive mechanical lock against the mounting face.

This mechanism ensures reliable resistance against lateral shear forces and prevents accidental disengagement caused by machine vibration or structural movement.

Technical Precision & Tolerance Control

Every Sinoboltco SNBLP000009 pin is precision-ground to strict engineering tolerances:

Shaft Diameter (ΦA) Tolerance: -0.08mm / -0.04mm, guaranteeing smooth slide-fit insertion into standard H7/f7 reamed location holes without mechanical binding or slop.

Grip Length (L) Tolerance: +0.5mm/ 0 mm, ensuring precise stack-up clamping across target plates and fixture walls.

Applications

CNC machining fixtures and welding inspection jigs

Robotic end-effector tooling and modular automation lines

Packaging, printing, and processing machinery guide rails

Aircraft ground support equipment and military hardware sub-assemblies

Quick-change stage lighting trusses and commercial fitness equipment

Product Advantages 

All-Stainless Internal Components: Pin body, spring, push button, locking balls, and split ring are made of stainless steel for corrosion resistance and operational longevity.

Ergonomic L-Handle Design: Ideal for restricted space applications where straight push-pull clearances are limited, allowing maximum manual leverage.

Vibration-Proof Positive Lock: Spring-driven ball expansion prevents accidental ejection during dynamic equipment operation.

Precision Tolerance Machining: Tight shaft diameter tolerance (-0.08 / -0.04mm) maintains exact alignment repeatability.

Integrated Anti-Loss Ring: Includes a stainless steel split ring on the handle for effortless attachment of safety lanyards or retaining cables.

Versatile Standard Sizing: Available in 8 standard metric shaft diameters (5 mm to 25 mm) and grip lengths up to 100 mm.

B2B Customization Ready: Sinoboltco provides technical design support, custom grip lengths, and OEM bulk supply.

Key Features

Stainless Steel Construction: Pin body, spring, actuation button, and locking balls resistant to rust and chemicals.

Aluminum L-Handle: Lightweight aluminum handle body for rapid single-handed operation in tight quarters.

Push-Button Quick Release: Retracts locking balls instantly for fast setup and changeovers.

Precision Shank Tolerances: ΦA shank ground to -0.08 / -0.04 mm for accurate locating fit.

Grip Length Range: Standard stock lengths L = 10 mm to 100 mm (tolerance +0.5 / 0 mm).

Loss-Prevention Ready: Fitted with stainless split ring for lanyard attachment.

Tool-Free Operation: Eliminates cotter pins, nuts, and wrenches on production lines.
