Fasteners organized by assembly function
The catalogue separates machine threads, self-tapping and triangular thread-forming designs. Buyers can start from the mating component and assembly route instead of selecting on appearance alone. [1]
Shantou Hongsheng supplies machine, self-tapping, thread-forming and custom screws in steel, copper and stainless steel for component assembly. Its catalogue distinguishes thread forms, head styles and finishes, including unusually long machine screws.
What the published manufacturing scope means for a buyer.
Shantou Hongsheng Bolt Industrial Co., Ltd. presents screw and fastener manufacturing in Shantou, Guangdong. The company describes production to specified GB, JIS, ISO, DIN and ANSI requirements and development of custom hardware. The reviewed catalogue is most useful when translated into a drawing-controlled fastener enquiry: head geometry, drive, thread, substrate, material and finish determine which advertised family is relevant. [2]
The catalogue separates machine threads, self-tapping and triangular thread-forming designs. Buyers can start from the mating component and assembly route instead of selecting on appearance alone. [1]
A reviewed 304 stainless-steel listing describes a long machine screw and a split-die production route. This is specific evidence for discussing a drawing-led part, rather than a promise of unlimited length or every size. [3]
The company lists iron/steel, copper and stainless-steel processing. Its illustrated listings distinguish untreated stainless steel, hardened carbon steel and plated finishes; material, hardness and coating should be specified separately. [2]
CNFX synthesis of the company’s published information.
Published product families and available services.
The reviewed long-screw listing identifies a 304 stainless-steel M3 example with a listed length of 140 mm. Its title and head-type table differ, so a signed drawing should establish the head and thread dimensions before ordering. [3]
The range includes conventional self-tapping and triangular thread-forming screws. A reviewed 410 stainless-steel listing gives an M5 x 8 mm example; another field incorrectly refers to a nut. Specify the actual thread profile, pilot hole, substrate and assembly test. [4]
The catalogue offers combination screws, step screws and non-standard parts. Define captive washers, shoulders and tolerance stack-ups in the drawing; these families are not interchangeable with ordinary machine screws. [1]
Published processes, organized by production stage.
The company describes producing standard and customer-designed screws. Agree the governing standard and revision or an approved non-standard drawing, including head, drive and thread acceptance. [2]
The long-screw and triangular-thread listings name split-die equipment. These pages support a discussion of those parts; they do not prove an entire machine inventory or that all finishes are performed in-house. [3]
The triangular-screw page mentions cleaning/passivation while other catalogue entries describe plating. Confirm the actual material/finish combination and an approved sample before the production order. [4]
Inspection, testing and project documentation.
The homepages state IATF 16949:2016. Certificate holder, site, number, scope and current validity were not independently checked; the profile does not award a certification badge. [1]
The long-screw title and head table conflict; the triangular-screw thread field includes unrelated nut wording. An approved drawing and inspection report should take precedence over those catalogue fields. [3]
Specify thread gauges, head/drive dimensions, hardness where relevant and coating acceptance. Salt-spray duration, sample preparation and test method must be tied to the offered finish; no general corrosion-life guarantee is adopted. [2]
Published product uses; no independently verified customer programme is implied.
The company lists electrical appliances, computer equipment and tools. Select the screw against the housing or mating thread, rather than treating a listed industry as evidence of a named customer programme. [2]
The long stainless-steel listing is relevant to assemblies needing an extended fastener. Confirm straightness, threaded length, drive access and head clearance on the actual part. [3]
CNFX procurement assessment.
Hongsheng is relevant to drawing-led sourcing of small and custom assembly screws, especially where thread form, length and material distinguish the part. Resolve catalogue inconsistencies through sample approval and measurable inspection requirements. Website equipment, output and certification claims are not independently audited.
