uxcell 3Pcs Retractable Indexing Plunger Pin M6 Steel Telescopic Lock

Description

Product Overview

The uxcell 3-piece retractable indexing plunger pins are engineered for precision fastening in demanding industrial environments. Each pin measures 41.5 mm × 15.5 mm (1.63 in × 0.61 in) and weighs only 0.64 oz, offering a compact yet robust profile that fits tightly into standard M6 threaded holes. Constructed from high‑grade stainless steel with a white‑washed surface, the pins combine corrosion resistance with a sleek appearance that endures exposure to moisture, chemicals, and abrasive wear. The telescopic design incorporates a 9.5 mm × 4 mm (0.37 in × 0.16 in) plunger shaft, delivering a reliable locking depth while maintaining a low overall height for seamless integration into tight assemblies. At the heart of each pin lies a precision‑engineered spring that provides consistent tension throughout the retractable cycle. The spring is calibrated to a 1 mm (0.04 in) pitch, ensuring that each turn of the L‑shaped handle advances the plunger by a predictable amount, which is essential for repeatable indexing in CNC machines, jig fixtures, and assembly lines. The L‑shaped handle itself is forged from the same stainless‑steel body, offering a solid grip that resists slippage even when operators wear gloves or work in oily conditions. This ergonomic design reduces the effort required to lock or release the pin, speeding up changeover times and minimizing operator fatigue. The pins are supplied in a set of three, each featuring a distinct color‑coded cap that corresponds to the thread size and intended load rating, simplifying inventory management for large workshops. Available thread sizes range from M6 up to M16, with a standard 1 mm pitch that matches common industrial fasteners, allowing the pins to be used interchangeably with existing hardware. The color‑coded caps—ranging from red for M6 to blue for M16—provide a visual cue that speeds up selection and reduces the risk of installing the wrong size. All dimensions, including the 17 mm (0.67 in) thread length, are clearly stamped on the shank for quick verification on the shop floor. Engineering tolerances for the uxcell plunger pins are held to ±0.02 mm, guaranteeing that the telescopic travel remains consistent across every unit in the batch. This precision is essential when the pins are employed in high‑speed automation lines where even a millimeter of variance can affect downstream processes. The pins also meet RoHS compliance, ensuring that no hazardous substances are present in the alloy or surface coating. Compatibility with a wide range of industrial standards, such as ISO 2768‑1 for general tolerances and ANSI B18.2.1 for spring dimensions, makes the product a versatile component that can be integrated into existing engineering drawings without the need for redesign. The shipping package is engineered to protect the delicate spring mechanism while minimizing material waste. Each three‑piece set is encased in a recyclable polypropylene sleeve that conforms to the pins’ shape, and a thin layer of biodegradable foam provides cushioning against shocks and vibrations during transport. The packaging bears clear labeling that includes the SKU, thread size, and color code, enabling warehouse staff to quickly locate the correct variant. By using recyclable and biodegradable materials, uxcell reduces its environmental footprint and complies with many customers’ sustainability requirements, making the product suitable for green‑focused procurement programs.

Usage

In CNC machining centers, the retractable indexing plunger pins serve as quick‑change fixtures for locating workpieces on the table. By inserting the pin into a pre‑drilled M6 hole on the fixture plate, operators can lock the workpiece in a repeatable position, then release it with a single turn of the handle to swap out the part for the next machining cycle. This reduces setup time dramatically, which is especially valuable in high‑volume production where every second counts. The pins also function as safety interlocks, preventing accidental movement of the spindle when the handle is locked in the closed position. Installation is straightforward and requires only a standard hex nut and a screwdriver. First, insert the plunger shaft into the pre‑drilled M6 hole until the threaded portion engages the nut. Next, turn the L‑shaped handle clockwise until the pin locks into the desired position; the audible click confirms proper engagement. To release, simply rotate the handle counter‑clockwise, and the spring will retract the pin, freeing the hole for the next operation. Because the mechanism is fully mechanical, no batteries or external power are needed, making the pins ideal for remote or off‑grid applications. While the pins are designed for durability, regular inspection helps maintain optimal performance. Users should check the spring tension periodically and replace any pin that shows signs of deformation or corrosion. The stainless‑steel construction allows cleaning with mild detergent and a soft brush; abrasive cleaners should be avoided to prevent surface scratching. When stored, keep the pins in a dry environment and protect the L‑shaped handles with a light oil coating to guard against rust in humid climates. Field technicians often appreciate the intuitive operation of the L‑shaped handle, which requires no special tools beyond a standard screwdriver for the initial nut installation. Training sessions can be completed in under ten minutes, as the visual color‑coded caps provide immediate identification of the correct pin size. For environments with limited lighting, the caps are also printed with high‑contrast markings that remain legible after exposure to oil or grime. Regularly scheduled checks—such as a quarterly visual inspection and a semi‑annual spring tension test—ensure that the pins continue to deliver reliable performance throughout their service life. All uxcell plunger pins comply with CE marking requirements for mechanical safety components, and they have been tested according to EN 1317 standards for road restraint devices, confirming their reliability under dynamic loads. In addition, the pins are designed to meet OSHA guidelines for hand‑tool ergonomics, reducing the risk of repetitive‑strain injuries during frequent operation. When used as part of a safety interlock system, the pins provide a fail‑safe condition: if the handle is not fully engaged, the spring will automatically retract, preventing accidental locking of machinery. Proper labeling and lockout‑tagout procedures further enhance workplace safety.
