At Kang Ding, we offer a complete range of screws fastener services, including
Cold heading, forging, turning and post-machining. We make pressure forging,
turning fastener bolt for export and also create the highest quality bolt parts
available in China, with economical prices that cannot be matched elsewhere. When
you send us your 3D product design for a free quote, our engineers will review
your design to ensure it is optimized for manufacturing.
What Is Screws Fastener?
Screws Fastener are a class of mechanical parts that are used for fastening
connections and are widely used. It is characterized by a wide variety of
specifications, performance purposes vary, and standardization, serialization, the
degree of generalization is very high. We provide fasteners bolt parts in Carbon
Steel, Alloy Steel, Stainless Steel etc.
Advantages Of Screws Fastener12.9 Level High Strength Fastener Bolt
Product classification widely, include: Screws, Nuts bolts, rods, rivets, and
other fastener Drywall screw, chipboard screw, hex head self tapping / drilling
screw, pan head, pan framing head, modified truss head screws etc.
Widely used in a variety of machinery, equipment, vehicles, ships, railways,
bridges, construction, structure, tools, instruments, meters and other products.
Surface finish and dimensional stability are excellent
Complex geometries can be made that require
It is great for medium to larger rooms parts that would slower and more
expensive to machine

Fastener Bolt Manufacturing Process
The Screws Fastener Manufacturing Process
At Kang Ding, a leader in China's bolt processing technology, In particular to a
primary forming Screws processing process, the method comprises the following
steps:1. cut material;_ First upsetting;_ two upsetting; _ three upsetting; _
final heading forming;
The process features: process through a molding die can be completed by four-bit
bolt forming machine extrusion, does not produce any waste, In the four-bit bolt
forming machine, new technology than the old process materials to save 5%, there
is no other extra redundant process, which greatly reduces the cost, effectively
control the cost, reduce the labor intensity of the staff, to ensure the reliable
quality of the product.
We pay special attention to certain key areas that must be controlled carefully.
These include wall thicknesses, draft angles, overhangs and the locations of
parting lines and ejector pin marks.
Screws fastene almost always requires some form of post-machining to provide
features that Screws fastene alone cannot provide. Using our in-house AddSub®
service this is a fast and easy process where material is removed by CNC milling
and turning, drilling, or grinding. We also have a range of other finishing
processes to ensure that you get the look you want.
Materials Used In Screws Fastenerstainless Fastener Bolt
Using the correct material is critical to the success of your project. We use
carbon steel (low carbon steel, medium carbon steel, alloy steel), stainless
steel, copper three kinds of materials, through the restructuring of raw materials
→ cold heading forming → thread processing (rolling wire or threading) → heat
treatment → surface treatment → sorting packaging, 10.9 above the general use of
heat treatment after the rolling process.
stainless Screws Fastener→ steel Stainless steel bolts are made of stainless
steel bolts, there are stainless steel SUS201 bolts, stainless steel SUS304 bolts,
stainless steel SUS316 bolts, stainless steel SUS316L bolts. the performance grade
of stainless steel bolts, studs and bolt is divided into 10 grades: from 3.6 to
Copper Screws Fastener→ Copper bolt material should meet the GB / T 3098.10-1993
"fasteners mechanical properties of non-ferrous metal manufacturing bolts, screws,
studs and nuts" requirements.
Carbon steel Screws Fastener→
Screws standard parts are mainly carbon steel bolts. Carbon steel in the
proportion of carbon content, divided into low carbon steel, carbon steel and high
carbon steel and alloy steel.
1, low carbon steel C% ≤ 0.25% domestic is often referred to as A3 steel. Foreign
basic known as 1008,1015,1018,1022 and so on. Mainly used for 4.8 grade bolts and
4 nuts, small screws and other products without hardness requirements. (Note:
drilling tail nail mainly with 1022 material.)
2, carbon steel 0.25% 0.45%. Currently on the market basically did not use
4, alloy steel: in the carbon steel by adding alloying elements, increase the
steel of some special properties: such as 35,40 chromium molybdenum, SCM435,
10B38. 12.9 grade alloy steel hexagonal screws mainly use SCM435 chrome molybdenum
alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo.
Fastener Bolt Surface FinishingSurface Finishing
Many finishing options are available for your Screws Fastener project including
Oxidation (blackening), Phosphating, Plating, Electrophoresis, Chemical conversion
Film, Coating, Galvanized, Nickel plating, Silver plating , Electroplating copper,
Cadmium plating, Chrome plating, Hot dip zinc, dacromet and much more. We can
advise you on the best choices for your design.
Quality And Inspection
At Kang Ding, we take quality seriously with a quality control team dedicated to
inspection of every part we make. We have invested in advanced inspection and
testing equipment to verify that your fastener bolt parts are made with exactly
the material you ordered. We are ISO certified and provide certification documents
with every shipment.
