Because of over half a century our manufacturing technology, adopted fiber-reinforced thermoplastic resin, 

know-how and technology of mold design for achieve high strength, KYOUJIN is born.

KYOUJIN is An engineering plastic with PA66 as the base polymer and reinforced with 60% glass fiber.

Continuous use temperature is 65°C/149°F,Flammability is UL94 V-HB

It has the highest strength among engineering plastic bolts that can be mass-produced.The tensile breaking load at M12 reaches 17,492N

Specific gravity is 1/5 of iron, insulating, heat insulating, non-magnetic, and resistant to rust.

Alternative metal screws are widely used in various industries such as robotics, construction, electronics, automobiles, sports, etc.

Use RoHS2 compliant raw materials.

◆Black spots may occasionally appear on the external surface.

◆Gate residue of screw head is 5% or less for length (L).

◆If screw is used with a nut, we recommend using the screw and nut made of the same material.

◆If screw is used with a female threaded part, we recommend maximum depth of 20 mm.

◆Values in the table are for reference purpose only, and they are not guaranteed values.

◆Please use torque driver or torque wrench for fastening. Recommended fastening torque is 50% of the torsional rupture torque.

◆Since heat resistance and chemical resistance change based on usage conditions, please test under actual usage conditions beforehand.

◆Discoloration may occur depending on lot and various conditions.

◆Sizes, shapes and manufacturers of raw materials may change without notice.
