NRH R7956-6-80 is a robust and straightforward spring pin latch - also referred to as a manual pull-pin latch or spring-loaded locking pin - engineered for secure, tool-free fastening in demanding applications. Constructed from durable SPCC steel and finished with a protective blue zinc plating, this heavy-duty latching solution offers excellent corrosion resistance and longevity. The defining feature is its solid 6mm diameter insert rod coupled with a high-tension coil spring. Operation is simple and reliable: pull the rod to retract, release for automatic spring locking. Weighing only 35g with a compact total length of 74mm, it delivers a potent yet space-saving latching mechanism. As a product of NRH Box Hardware with expertise since 1996, this industrial latch is manufactured under an ISO 9001:2000 certified system and complies with SGS, REACH, SVHC, and RoHS standards. OEM/ODM services are available for custom configurations.
Primary Applications
This versatile spring-loaded latch is designed for securing robust enclosures across various sectors:
- Industrial Toolboxes & Machine Guards: For heavy-duty tool chests, welding equipment cases, and machinery access panels - an ideal heavy-duty fastener.
- Electrical & Server Enclosures: As a reliable manual locking pin for control cabinets, server racks, and modular panels.
- Transport & Logistics Cases: Provides secure closures for shipping containers and equipment transit boxes as a positive locking mechanism.
- Agricultural & Construction Equipment: Durable latching for vehicle-mounted toolboxes and field service enclosures.
How It Works (Operating Principle)
The latch operates on a fundamental spring-loaded principle - essentially a spring pin mechanism. The internal compression spring holds the 6mm insert rod firmly in the extended (locked) position.
- To Unlock: Manually pull the insert rod outward against the spring pressure. This action compresses the spring and retracts the rod, disengaging the strike.
- To Lock: Align the door or panel and simply release the rod. The spring automatically drives the rod forward to engage the strike point, securing the assembly with automatic spring return.
Features & Specifications
- Heavy-Duty 6mm Insert Rod: The substantial 6mm diameter provides superior shear strength and resistance for reliable, long-term engagement - a true heavy-duty latch.
- Simple & Positive Manual Action: Direct pull-to-open operation offers intuitive, tool-free, and fail-safe functionality - a genuine manual fastener.
- Automatic Spring Return: A high-quality spring ensures consistent, automatic locking upon release every time, functioning as a self-latching pin.
- Durable Construction: SPCC steel body ensures structural integrity, while blue zinc plating provides robust protection against rust and wear - ideal for industrial environments.
- Engineered for Secure Mounting: Designed with a reinforced base plate featuring multiple standardized mounting holes for a solid and permanent installation. Refer to the official engineering drawing for precise mounting specifications.
