Slotted Spring Pins
This product features a hollow, elastic structure, made of carbon steel/stainless steel, and cold-forged. It possesses excellent elasticity and toughness, and after being inserted into the hole, it expands elastically to tighten, adapting to hole misalignment, providing excellent anti-loosening performance, and facilitating easy disassembly. The full range includes open and closed types, and is readily available. The surface is treated with rust prevention, undergoes quality control, complies with environmental regulations, and compliance documentation can be provided. Custom sizes and wall thicknesses are supported.
