Product Description

Product Description

Detail shotThis is a stainless steel csk-head solid rivet. It is manufactured by cold heading or hot forging using 304 or 316 stainless steel wire. The surface is polished to a natural finish or undergoes passivation treatment. The product consists of csk head and a cylindrical solid shaft, forming an integrated structure. It has no hollow part, no threads, and no core rod. By passing the shaft through the through-hole of the connected component, and using pressure or impact force to cause the tail to undergo plastic deformation to form a second anchoring head, a permanent mechanical connection is achieved. This "solid one-piece, permanent locking" design ensures excellent reliability when subjected to impact, vibration, and alternating loads. It is a classic fastening solution for fields such as bridges, ships, aviation, and heavy machinery, which have undergone over a century of industrial application verification.FeatureOverall solid structure
From the head to the tail, it is a continuous solid metal without any hollow parts, welds, or assembly interfaces. The material fibers flow along the contour, and the shear strength and tensile strength reach over 90% of the base material.
Large flat round head design
The diameter of the head is 1.8 to 2.5 times that of the rod diameter. It has sufficient thickness, providing a large bearing area and axial positioning. The surface is smooth and can be used as a decorative surface or functional bonding surface.
Cylindrical smooth rod combination
The diameter accuracy of the rod body is H11 grade, with a surface roughness of Ra ≤ 3.2 micrometers. It forms a gap or light interference fit with the mating hole, facilitating insertion and precise positioning.
Tail forging forming
During installation, the tail undergoes plastic deformation under pressure or impact, forming a second bearing head that is symmetrical to or slightly smaller than the head. After deformation, the metal becomes denser and its strength does not decrease but increases.
Pure material and corrosion resistance
The 304/316 stainless steel body inherently possesses corrosion resistance. There is no risk of coating detachment. Its service life in corrosive environments such as marine, chemical, and food industries is much longer than that of carbon steel galvanized rivets.Specification

Grade	304;316L;17-4ph
Diameter	2 MMto 20 MM, corresponding to the standard series GB/T 867, DIN 124, and ISO 1051. For larger diameters, hot forging is required for manufacturing.
Head Type	Flat head (general type), semi-round head (decorative type), countersunk head (smooth appearance), large flat head (anti-collapse protection for thin plates)
Length	8mm to 150mm. Based on the total thickness of the insert plus the forging allowance, customizations for extremely long specifications are available.
surface treatment	The original color, brushed finish, mirror polishing, passivation treatment, and electrolytic polishing are all implemented to meet the differentiated requirements for appearance and corrosion resistance.

Application Scenario

ApplicationBridge steel structure
Permanent connection of steel truss node plates and longitudinal and transverse beams of the bridge deck, combined with high-strength bolts to form a composite connection, capable of bearing historical-level traffic loads.
Ship and marine engineering
Structural riveting of hull framework, deck machinery, and offshore platforms, 316 material resistant to seawater corrosion, ensuring connection integrity for a century-old ship.
Aerospace vehicles
Traditional connections of aircraft fuselage skins and frames, fuel tanks of spacecraft, solid rivets as the classic fastening method for aluminum alloy structures, reliability verified through flight tests.
Heavy mining machinery
Movable parts of crushers, ball mill shells, and chassis of excavators' bases' wear-resistant connections, do not loosen under impact loads, extending the equipment's major overhaul cycle.
Rail transit vehicles
Steel structure restoration of historic steam locomotives and freight carriages, as well as decorative metal plate fixation of modern tramcars, combining functionality with retro aesthetics.
Pressure vessel manufacturing
Connections of strengthening rings, tube plates, and shells of boilers and storage tanks, solid rivets providing superior sealing performance compared to welding, suitable for maintenance scenarios where firework is not allowed.
Cutting tools and hardware
Hinged shafts of scissors, pliers, and lock tongues of traditional locks, solid rivets providing smooth and durable rotational connections.Main Product
