DSN Type Distance Spacers with Wrench Flat
Distance Spacers with Wrench Flat (DSN type) are engineered for precise spacing between plastic mold components, helping maintain proper alignment during assembly and molding. The wrench-flat end improves handling and secure installation for consistent results on the shop floor.
- Wrench-flat design supports controlled tightening and easy installation
- DSN type construction maintains stable component separation in mold builds
- Outer diameter options support flexible fit for different mold part layouts
- Used with screw plug setups to manage spacer length cut and assembly positioning

Product Guide
Application Scenarios+
DSN type distance spacers with a wrench flat are used in plastic injection mold assembly to set and maintain the designed gap between mold components such as plates, inserts, or housings. In the shop floor, the wrench-flat end enables controlled tightening (with a suitable wrench) so the spacer seats repeatably and helps preserve parallelism during build-up.
- Automotive and consumer electronics connector molds: where small dimensional variation can affect gate alignment and shutoff consistency, the spacer’s stable separation helps maintain component positioning through repeated assembly cycles.
- Medical device housing molds: when precision spacing is required for cavity/core alignment, DSN geometry supports consistent placement during screw plug assisted assembly.
- High-mix tooling builds: the multiple outer diameter (D) options support different mold part layouts while the length-cut range supports customization.
This variant is suited to these applications because the wrench-flat design simplifies installation and the DSN spacer construction is intended to maintain stable spacing between mold components.
Material & Process Details+
The provided product specifications describe dimensional features (outer diameter D and cut spacer length LC) and installation convenience, but no steel grade, hardness (HRC), heat treatment, or coating information is included in the input data.
Because material properties such as wear resistance, toughness, and machinability depend on the actual steel and heat-treatment condition (for example, quenched & tempered, nitrided, or pre-hardened steels), those characteristics cannot be stated factually for this DSN distance spacer variant without a listed material specification.
- Note: If you share the steel grade or material listing for part 110200175720, the material_html can be updated to include equivalency (e.g., AISI/H13/M2 equivalents), target hardness in HRC, and relevant heat-treatment steps.
Sizing & Selection Guide+
Select the correct DSN distance spacer by matching the required mold build gap to the spacer’s cut length (LC) and choosing an appropriate outer diameter (D) that fits your component layout.
- Spacer length (LC): Choose an LC in the range 55 ～ 95 mm based on the axial distance you need between the mating mold components. Use the “spacer length cutting” capability to finalize the spacer length for the actual stack height.
- Outer diameter (D): Available options are 20, 25, 32, 38 mm. Pick the D that provides stable support and clearance relative to surrounding parts and fasteners.
When used in a build with screw plug setups (as referenced in the product description), ensure the spacer’s cut length positions the assembly correctly and prevents over-compression at tightening. While tolerance values are not provided in the input data, maintain installation consistency by verifying the effective stack-up height after cutting and tightening to the intended clamping condition.
Frequently Asked Questions
Which spacer length range (LC) is supported for DSN type distance spacers with wrench flat?+
The supported LC (spacer length cutting) range is 55 ～ 95 mm. Engineers should determine the required axial gap from the mold’s stack height and then select a spacer length within this range before finalizing by cutting.
What outer diameter (D) options are available, and how do I choose between them?+
Outer diameter D is available in 20, 25, 32, and 38 mm. Choose the D that matches your mold component layout and provides stable spacing without interfering with adjacent parts or fasteners.
How does the wrench-flat design affect installation in plastic mold assembly?+
The wrench-flat end is intended to support controlled tightening and easier installation. This helps improve repeatability during mold builds, which is important for maintaining alignment and separation set by the spacer.
Is this DSN spacer intended to be used with screw plug setups for positioning?+
Yes. The provided description indicates use with screw plug setups to manage spacer length cut and assembly positioning. In practice, engineers should confirm the effective stack height after cutting and before final tightening.
What material grade, hardness (HRC), and heat treatment should I expect for part 110200175720?+
The input data does not specify the steel grade, hardness (HRC), or heat-treatment condition for this product. To select based on wear resistance and toughness trade-offs, request the material specification listing for series code 110200175720.
