We have many years’ production and export experience for open end blind rivets.
Closed End Blind Rivet
Ningbo Teng Qi Fasteners Co., Ltd is a leading manufacturer of closed end blind rivet. Closed end blind rivets are composed of three parts: the rivet body, the core rod and the rivet cap. The rivet body is mainly made of aluminum alloy or stainless steel. It generally has high strength and corrosion resistance. The core rod is used to pull the rivet body into the the part of the workpiece, the rivet cap, is the part used to protect the head of the rivet. The closed end blind rivet has good hole filling performance, and the retained rivet core provides a strong vibration-resistant riveting. Our products have a good quality & price advantage and cover most of the European markets.
Hemlock High Strength Structural Blind Rivet
Ningbo Teng Qi Fasteners is a professional fasteners manufacturer. Hemlock structural blind rivets are the important products for our factory. Hemlock rivet is a structural rivet with excellent shear strength and tensile strength. It has high shock resistance and large blind end bearing area. It is not easy to deform. It provides a large back pressure bearing surface and is close to the back plate. It is suitable for riveting. Riveting fields that require high strength and sealing performance, such as riveting of thin plates. With excellent quality, reasonable price and best service,we hope to be your best partner in China soon.
Installation process:
1. Insertion: The blind rivet is inserted into a pre-drilled hole in the materials to be joined. The head of the rivet is placed on one side, and the mandrel tail sticks out on the other side.
2. Setting: To secure the joint, a specialized rivet tool is used. When the tool is activated, it pulls the mandrel’s head, causing the tail end to deform and expand inside the rivet body. This expansion creates a bulge on the blind side of the materials, effectively clamping them together.
3. Break-off: Once the mandrel has been pulled completely, it breaks off at a predetermined point. The remaining part of the mandrel is discarded, leaving the installed blind rivet securely fastened.
Manufacturing quality of blind rivets:
| Inspect Item | Detail |
|---|---|
| Dimensional Inspection | Critical dimensions such as bolt diameter, head width, head height, bolt length and thread length are checked using calibrated measuring equipment. Inspection is carried out according to the applicable dimensional standard or customer drawings to ensure consistent fit and interchangeability. |
| Thread Inspection | External threads are inspected using calibrated GO and NO-GO thread gauges to verify thread profile, pitch and dimensional conformity. Additional measurements can be performed when tighter thread tolerances or specific customer requirements apply. |
| Mechanical Testing | Mechanical properties are verified according to the specified material and strength grade. Depending on the applicable standard, testing may include tensile strength, yield strength, hardness and other required mechanical tests, with test results documented in the relevant inspection or material reports. |
| Surface & Coating Inspection | Bolt surfaces are inspected for appearance, defects, coating uniformity and other specified requirements. For coated fasteners, coating thickness and adhesion or other applicable coating characteristics can be checked according to the specified surface treatment standard. |
| Final Inspection & Testing | Before shipment, finished hex bolts undergo final inspection to confirm dimensions, thread quality, mechanical requirements, surface condition, marking and packaging. Inspection records and test reports can be provided according to the order specification and customer requirements. |
