Threaded Stainless Steel Ball Lock Pin – SNBLP Series (snblp000019)

Precision Quick-Release Locating for Industrial Machinery

The SNBLP Series (snblp000019) threaded ball lock pin from Sinoboltco provides high-repeatability positioning and quick locking for demanding tooling, fixture design, and automated assembly line environments. Engineered specifically to streamline tool-free changeover, the snblp000019 reduces downtime during workpiece setups, checking gauge operations, and module replacements.

Integrated Threaded End & Dual-Ball Locking Mechanism

Unlike conventional smooth-head quick-release pins, the snblp000019 features an integrated metric thread shank at the rear of the body. This design allows the main pin assembly to be permanently screwed into frame plates or fixture bases, serving as a captive, non-detachable locating unit. The tip contains a heavy-duty internal spring coupled with dual hardened locking balls. When inserted into the mating hole, the internal spring pushes the balls outward beyond the shaft diameter to engage a positive lock against axial tension. Pressing the internal button retracts the balls flush with the shaft outer diameter for immediate insertion or extraction.

All-Stainless Steel Construction for Harsh Environments

To ensure maximum corrosion resistance and mechanical endurance under wet, chemical, or outdoor conditions, the entire assembly—including the pin shaft, internal spring, and retaining balls—is manufactured from premium grade stainless steel. The precision ground pin shaft minimizes wear against bushing walls, preventing galling and maintaining tight tolerance fitting over thousands of actuation cycles.

Risk Mitigation via Material Futures Hedging

As a specialized B2B industrial manufacturer and raw materials commodities trader, Sinoboltco offers unique procurement advantages for OEM buyers and distributors. By leveraging stainless steel futures hedging (LME/SHFE nickel and alloy contracts), we help industrial clients lock in long-term stable unit costs for the SNBLP Series. This eliminates price volatility on high-volume supply contracts regardless of market surges.

Product Advantages

1. Complete Stainless Steel Construction: Pin shaft, internal spring, and dual locking balls are built entirely from stainless steel, delivering outstanding anti-corrosion and wear resistance in humid, chemical, or marine applications.

2. Captive Threaded Mount: The integrated thread shank allows permanent fixing to machine frames or fixture plates, preventing pin misplacement during rapid disassembly.

3. High Precision Fit: Ground shaft tolerances (-0.04 mm / -0.08 mm) ensure close clearance fitting, reducing play and optimizing repeatability in fixture alignment.

4. Tool-Free Efficiency: Push-button spring ball mechanism allows single-handed lock/unlock operations within seconds, dramatically reducing changeover times on production lines.

5. Raw Material Price Stabilization: Backed by Sinoboltco’s raw material futures hedging, long-term supply contracts are protected against global nickel and stainless steel market surges.

6. Custom Machining & Scalability: Flexible production capabilities support custom grip lengths, non-standard thread pitches, and special heat treatment options for OEM clients.
