Quality Inspection for Stainless Steel Pan Head Socket Head Cap Screws - Galvanized Expansion Bolts Stainless Steel – Aozhan

Description

304 stainless steel expansion screws generally refer to metal expansion screws. The fixation of the expansion screws is to use the wedge-shaped slope to promote the expansion to generate frictional gripping force to achieve the fixing effect. The screw is threaded on one end and tapered on the other. There is an iron sheet (some steel pipes) on the outside, and half of the iron sheet cylinder (steel pipe) has several incisions. Put them together into the hole made in the wall, then lock the nut, pull the screw out with the nut, and pull the taper into the iron sheet cylinder. , The iron cylinder is opened, so it is tightly fixed on the wall, which is generally used for the fastening of guardrails, awnings, air conditioners, etc. on cement, bricks and other materials. Widely used in environmental protection equipment, medical equipment, communication equipment, power facilities, electronic products, instrumentation, food machinery, petrochemical, ship assembly, pump valve piping, building curtain walls, open air, sports facilities, outdoor decoration, etc., 304 stainless steel It has good corrosion resistance, can keep the surface bright for a long time, and the material also meets the requirements of environmental protection.

Product features: fast and economical, reliable wall protection, simple structure, convenient installation. How to use: first drill a hole of the corresponding size in the foundation or wall, then put the bolt and expansion tube into the hole, then put the mounting hole on the mounting piece and the flat spring washer on the bolt in turn, and finally screw the nut in. Tighten. Matters needing attention: The depth of drilling is preferably about 5 mm deeper than the length of the expansion pipe in the specific construction; be careful not to unscrew the nut.
