Production process of hexagon socket head cap flange screws

Hexagon socket head flange bolts are a fastener widely used in machinery, construction, and other fields.

Hexagon socket head flange screws are a kind of hexagonal bolts; the following Fashway editorial tells you what process will be used in the production process:

1.    Cut off, using s

2.    pecial scissors in a single direction to cut the material stuck inside the shear mold into the embryo material we need.

2. A punch: This step is mainly after the punch die is placed on top of the embryonic material for extrusion in the slow molding and then pushes the embryonic material out.

3. Two punch: This and the above steps are almost identical. It is the second extensive mold, die extrusion, so that after processing, the embryo material will become flat and round.

4. three punch: this is the third time to process the mold. The hexagonal three-punch die Ren shears when the embryonic material hexagonal head slowly forms out of the embryonic material into the mold for the third time to hit the mold, and finally, when the head of the hexagonal is cut off when the production is completed.

Structure and characteristics of hexagonal flange bolts

1. Structure: Hexagonal flange bolts comprise a head, body, and tail. The head is an external hexagon that is easy to rotate using a wrench or wrench socket; the body is a straight rod that connects two parts; and the tail is threaded, which fixes and connects.

2. Features:

(1) The outer hexagonal head is easy to rotate and easy to use;

(2) The flange surface can increase the fastening force and improve the connection strength;

(3) High precision of rod body, stable and reliable connection;

(4) Excellent material, good corrosion resistance.

Hexagonal flange bolts Precautions for use

1. Before use, the hexagonal head and flange face should be checked for damage or deformation, and if any, they should be replaced;

2. care should be taken not to over-rotate or exert excessive force during use to avoid damage to the parts;

3. appropriate wrenches or wrench sockets should be selected for use and kept clean and dry;

4. When used, it should be tightened by the specified tightening torque to avoid under or overtightening.

Production process of hexagonal flange bolts

1. Material preparation: choose suitable carbon or alloy steel materials and conduct pretreatment processes such as cutting and forging.

2. Heat treatment: quenching and tempering the rod body to improve strength and toughness.

3. Forming: Cold extrusion molding or hot forging forms the outer hexagonal head and flange face.

4. Machining: Perform machining on the head and tail, such as cutting threads.

5. Surface treatment: Perform surface treatment processes, such as pickling, sandblasting, etc., to improve corrosion resistance.

6. Testing: Mechanical properties of the finished product, chemical composition, and other tests to ensure that the quality is qualified.

JIS High-Strength Steel Flanged Hex Head Screws: Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The zinc plating provides corrosion resistance in wet environments. Head height includes the flange. Length is measured from under the flange.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws: These Class 8.8 steel screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. All screws meet DIN 6921 specifications for dimensions. Head height includes the flange. Length is measured from under the flange.

Zinc yellow-chromate-plated screws resist corrosion in wet environments. They also meet ISO 898-1 specifications for materials. Black corrosion-resistant-coated screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

Medium-Strength Grade 5 Steel Flanged Hex Head Screws: Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The material meets SAE J429 specifications for quality. Dimensions meet IFI 111 specifications. Grade 5 steel hex head screws are marked with three radial lines. Head height includes the flange. Length is measured from under the flange.

Zinc-plated steel screws resist corrosion in wet environments. Black corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.
