Stainless Steel Threadless Straight Spring Loaded Plunger | snsp000003 from Shanghai sinoboltco Technology Co., Ltd.

As a dedicated industrial hardware supplier, Shanghai sinoboltco Technology Co., Ltd. delivers high-performance positioning solutions with our proprietary snsp000003 straight spring-loaded plunger series. This threadless, smooth-body indexing pin is optimized for repetitive mechanical locking, fixture positioning, and alignment tasks where space is limited and structural integrity is paramount.

To ensure maximum durability under harsh factory conditions, the entire assembly—including the outer sleeve, the flat-end locating pin, and the internal pre-compressed spring—is constructed from premium stainless steel. This material selection guarantees excellent wear resistance and reliable corrosion defense in humid, outdoor, or chemical-exposure environments.

Complete Technical Specifications & Matrix Engineers can seamlessly integrate the snsp000003 into their technical drawings by cross-referencing our standardized dimensional data based on precise outer diameter (Dh7) tolerances and stroke travel (S):

Dh7 Diameters Available: 2mm, 3mm, 4mm, and 5mm options, engineered to achieve a perfect interference fit within machined mounting holes.

Stroke Travel (S) Range: Covers options from 1.5mm up to 12mm, providing precise retraction depths for variable indexing configurations.

Calibrated Spring Force: Finely tuned from a minimum of 0.49N for delicate component indexing up to a maximum heavy-duty holding force of 7.06N.

B2B Ordering System & Custom Manufacturing To streamline procurement for international distributors and procurement managers,

our inventory follows a strict proprietary encoding rule: Type – Dh7 – S.

For Light Load requirements: Order as snsp000003-TL-Dh7-S (e.g., snsp000003-TL-4-6 for 4mm diameter and 6mm stroke).

For Heavy Load requirements: Order as snsp000003-TH-Dh7-S (e.g., snsp000003-TH-5-8 for 5mm diameter and 8mm stroke).

Common Application Scenarios

Automated assembly lines, indexing fixtures, and robotic positioning brackets.

Plastic injection molding dies, metal stamping toolings, and quick-change mold plates.

Electronic enclosure panel latches, industrial cabinetry locking setups, and switchgears.

Material handling systems, heavy-duty conveyor belt spacing controls, and pallet stops.

Product Advantages

Industrial-Grade Stainless Steel Supply: Manufactured completely from robust stainless steel raw materials, ensuring zero rust, long cycle lives, and zero coating peeling during high-frequency reciprocating compression.

Dual Load Classification System: Offers distinct Light Load and Heavy Load configurations within the same outer shell dimensions, allowing mechanical designers to adapt to varied pressing force demands without changing blueprints.

Cost-Reducing Press-Fit Design: The straight, threadless cylinder profile allows for direct press-in installation into pre-drilled holes, cutting out expensive thread-tapping procedures and speeding up bulk production runs.

Strict Dh7 Tolerance Standards: Every single lot undergoes strict quality control to maintain tight dimensional tolerances, guaranteeing that the plunger stays securely anchored inside the mounting hole under heavy operational vibrations.

Full OEM/ODM Support & Low MOQ: Backed by our integrated manufacturing capabilities, Shanghai sinoboltco Technology Co., Ltd. provides full support for customized non-standard travel strokes, special spring rates, and flexible sample testing for prototype approval.

 Product Features

Threadless straight cylinder shape for quick and flush press-in mounting without external fasteners.

Flat pin head configuration providing clean, face-to-face mechanical locking without scraping counter-surfaces.

Industrial internal spring, pre-stressed during factory production to maintain consistent rebound and prevent premature fatigue.

Verified spring force outputs ranging from a minimum of 0.49N up to 7.06N as detailed in our technical datasheet.

Clean, RoHS-compliant raw materials suitable for cleanrooms, medical device packaging, and food-processing equipment.
