Product Description

Characteristics and applications of Pan washer head tail cutting straw rope screws

System introduction

Pan washer head tail cutting straw rope screws is a kind of screw with drill bit.It is constructed by special electric tools,and drilling, tapping, fixing and locking are completed at one time.Pan washer head tail cutting straw rope screws are mainly used for connection and fixation of some thin plate parts,such as the connection between color steel plates and color steel plates,the connection between color steel plates and purl-ins,wall beams,etc.Their penetration capacity is generally not more than 6mm,and the maximum is not more than 12mm.Pan washer head tail cutting straw rope screws are often exposed outdoors and have strong corrosion resistance;The rubber sealing ring can ensure that the screw is impermeable and has good corrosion resistance.Pan washer tail cutting head straw rope screws are usually described by three parameters: screw diameter series,number of threads per inch length and screw length.The more threads per inch length,the stronger the self tapping ability.

Product differentiation

The Pan washer head tail cutting straw rope screws has high hardness, wide thread spacing,deep thread and rough surface,while the wood screw has the opposite.Another difference is more obvious.The rear section of the wood screw has no thread.The wood screw thread is thin,blunt and soft.The thread of straw rope screw is thick,sharp and hard.

Surface treatment

Most straw rope screws are coated with zinc or zinc phosphate. Cadmium plating is rarely used because of its high cost and toxicity.If appearance is important,nickel or chromium can be selected.

Main features:

Although there are many kinds of straw rope screws, they all have the following main characteristics:

(1) It is generally made of carburized steel(accounting for 99% of the total product).Stainless steel or non-ferrous metal may also be used.

(2) The product must undergo heat treatment.Carbon steel straw rope screws must undergo carburize treatment,and stainless steel straw rope screws must undergo solution hardening treatment.So that the straw rope screw can meet the mechanical performance and service performance required by the standard.

(3) The product has high surface hardness and good core toughness.That is,"soft inside and hard outside".This is a major feature of the performance requirements of straw rope screws. If the surface hardness is low,it cannot be screwed into the base; If the toughness of the core is poor,it will break once screwed and cannot be used.Therefore,"soft inside and hard outside"is that straw rope screws meet the requirements of service performance.

(4) The product surface needs surface protection treatment, generally electroplating treatment.Some products need phosphate treatment(phosphating) on the surface.For example, the straw rope screws of wallboard are mostly photostatted.

(5) It is produced by cold heading process.It is recommended to use high-speed cold heading machine,high-speed wire rolling machine or high-speed planetary wire rolling machine to ensure product quality.The straw rope screw produced in this way has good head forming and high thread quality.
