Products Description
Black Zinc Stainless Steel Self-Drilling Screw With Epdm Washer is a new invention in recent years. Screws are a common term for fasteners, a daily spoken word.The tail of the self-drilling screw has a tail-drilling or pointed tail shape, and no auxiliary processing is required. It can be directly drilled, tapped and tightened on the set material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and holding power are high, and it will not loosen after a long time after combination. It is easy to complete the operation by using safety punching and tapping at one time.
Hex Head Self Drilling Screw with Epdm Washer:
Head Type: Hex head/ Hex Flange Head
Standard: DIN/ANSI screw standards
Material: C1022, C1022A, Carbon Steel, Stainless Steel
Surface treatment: Zincplated, Painted
1. Self-tapping screws: mechanical performance requirements
1. Heart hardness: standard value HRC28-38. The test is carried out on a section 1-2 times the nominal diameter from the tail. If the nominal length is too short, it can be embedded first, and then the hardness is measured.
2. Surface hardness: standard MIN HV450.
3. Carburized layer: standard 4#-6#:0.05-0.18mm, 8#-12#:0.10-0.23 mm, 14#:0.13-0.28 mm. The main purpose of carburization is to increase the surface hardness and ensure the strength of the teeth. If the decarburization is too deep and the carburization is insufficient, the strength of the teeth will not meet the requirements, that is, the teeth will be damaged during the screwing test.
