Socket Cap for BH R58

Specifications

How to choose Masking cap

Points to check when selecting, with the values for this product (BHG20).

1. 1. Check the relationship between fitting diameter and inner diameter

   The basic principle is to make the cap's inner diameter slightly smaller than the diameter of the bolt or pin, relying on rubber stretch to hold it. If the inner diameter is too large, the cap may come off during baking or transport; if too small, it becomes difficult to fit and may tear. Verify the fitting diameter specification against the actual dimensions of the target.

2. 2. Assess fit using the inner diameter dimension

   Even with the same fitting diameter, the inner diameter setting changes the tightness of the grip. For threaded parts, base the selection on the outer diameter of the thread crest. In processes such as powder coating, where paint tends to wrap around, choose a dimension with enough interference to prevent gaps.

3. 3. Secure the required length with overall length

   The overall length determines the protected range. Measure the thread engagement length or the exposed length of the contact and select a length that fully covers it. If the cap is too long, it will mask surfaces that should be painted, so also confirm the boundary position for the color division.

4. 4. Select a material that withstands the baking temperature

   Powder coating and baking finishes expose parts to high temperatures in the oven, so choose a product whose heat resistance exceeds the process baking temperature and holding time. Silicone is generally preferred where heat resistance is important. If heat resistance is insufficient, the cap may soften or deform, allowing paint to penetrate.

5. 5. Confirm the material suits the process and chemicals

   This product: Material Silicone

   Silicone offers excellent heat resistance, while EPDM is used for weather resistance and resistance to certain chemicals. If the cap contacts plating or pretreatment chemicals, verify its resistance to those chemicals. For repeated use, ease of peeling off the coating is also a factor in material selection.

6. 6. Choose a shape that suits the mounting target

   Straight types suit bolts and pins in general, and flanged types suit locations where the bearing surface also needs covering. Ribbed types resist slipping off and are used for masking contacts. Model-specific products exist for paint hanger sockets, and attention must be paid to differences in insertion direction (horizontal, or vertical and horizontal).
