CBA Type Hex Socket Head Cap Screws - Through Hole

Through-hole mold fastening for injection tooling where repeatable clamp positioning and secure retention are critical. These CBA-type hex socket head cap screws use a through-hole arrangement that helps align mating components during mold build-up and service.

In automotive connector and sensor housings mold assemblies, they are commonly used to secure cavity and core support plates and adjuster components. The coarse socket head supports controlled tightening, helping maintain clamp integrity in high-stress, vibration-prone production cycles.

For multi-cavity consumer product molds (e.g., appliance handles, grips), the screws’ through-hole design simplifies installation through the stack and supports consistent torque transfer across fastener locations. The availability of full thread or with incomplete threaded part allows proper engagement depth to match the thickness of mold base components.

• Through-hole configuration supports stable alignment during assembly
• Coarse socket improves driving control for reliable clamp force
• Full/incomplete threading options support different stack-up thicknesses

Material and heat-treat properties are not specified in the provided product metadata for this CBA type hex socket head cap screw through-hole variant. Therefore, hardness (HRC), wear resistance, toughness, and specific heat treatment state (e.g., quenched & tempered, nitrided) cannot be confirmed from the input data.

When selecting fasteners for plastic mold assemblies, engineering review should focus on the thread engagement length, the expected assembly torque, and any special requirements such as repeated disassembly or exposure to molding chemicals.

• Hardness (HRC): not provided in the dataset
• Heat treatment: not provided in the dataset
• Wear resistance vs. toughness: depends on the actual steel grade and tempering condition, not provided

If you can share the requested steel grade or the supplier datasheet for series code 110200132660, the material section can be updated with confirmed hardness and treatment details.

Use the nominal diameter M and length L to match your mold stack-up and required thread engagement. This product is available for M = 5, 6, 8, 10, 12, 16.

Select L (10 ~ 100 mm) so the threaded portion provides the intended engagement without bottoming out in blind counterbores. For the provided inner diameter range, d = 2 ~ 9 mm, confirm that your clearance/through-hole geometry in the mold components supports the screw’s through-hole configuration while maintaining alignment.

• Diameter match: choose the same M as the tapped/engaging feature requirement
• Length match: choose L within 10–100 mm for correct clamp stack coverage
• Threading option: use full thread where full engagement across the mating thickness is desired, or with incomplete threaded part to control engagement depth for different assemblies

Tolerance guidance (e.g., fit class) is not provided in the dataset. In practice, verify hole and thread tolerances against your mold drawing standards to ensure consistent clamp force and assembly repeatability.
