Product overview

Right angle fasteners must be manufactured in accordance with the drawings approved in accordance with the prescribed procedures. The material of fastener shall conform to the mechanical properties specified by KTH330-08 grades in GB9440. The production of fasteners must be batched according to the batching ratio specified in the process. Fasteners heat treatment strictly implement the temperature and time of each stage of the process. Fasteners shall be processed in strict accordance with the process, and the bonding surface between the fastener and the steel pipe shall be tested and reshaped to ensure the requirements of anti-slip and tensile properties of the fastener. Fasteners (except the base) must be tested by 70N.m torsion torque pressure test, and no damage is allowed. Anti-sliding performance of right angle fastener, when P = 14KN, △ 2 ≤ 0.5mm. Tensile performance of butt fastener: when P = 6KN, △ 2 ≤ 0.2mm. No more than one sand hole with a sand hole area greater than 10 mm² is allowed, and the cumulative area shall not be greater than 40 mm².

Since the right-angle fastener must have a certain load-bearing capacity during use, and at the same time he must have a certain resistance to deformation, he should be fixed as firmly as possible during use to prevent the risk of loosening and slipping of the bracket. Its material is considered. Different materials must have different strengths, so generally choose materials with higher hardness as right-angle fasteners. There are many right angle fasteners on the market now, but generally right angle fasteners have very strict production standards. Therefore, a detailed understanding of the right angle fastener should be carried out before use.

　　Performance characteristics

Right angle fasteners are also known as cross fasteners, scaffolding and just hanging with the use of a common fastener, his main features in the following areas:

Excellent breaking resistance-all-steel cold-pressed structure is advanced, all-steel cold-pressed forming, strength and toughness exceed national and international standards, completely eliminating the hidden danger of scaffold collapse caused by fastener fracture of cast iron old fasteners.

Excellent anti-sliding-large surface bonding area ensures that the steel pipe and the fastener are in a surface bonding state, and the bonding area is large, which overcomes the point or line bonding of the old fastener and the steel pipe, eliminates the hidden danger of steel pipe slipping, and thus ensures and improves the overall mechanical performance and safety performance of the scaffold.

Anti-stripping strong-new connection, to ensure that in the case of steel pipe variation, the fastener can always be fixed vertically and correctly, eliminating the possibility of steel pipe slippage.

Strong anti-rust-shield treatment, the whole piece has been passivated and galvanized double anti-rust treatment, its anti-rust ability is greatly improved, and its service life far exceeds that of old fasteners.

Fast and lightweight-structural optimization, fasteners light, beautiful, comfortable, loading and unloading speed, labor intensity is reduced.
