Product Description

Product Introduction:

Screws are fasteners similar to bolts but with different applications. Their core characteristic is that they usually do not require a nut. Instead, they are screwed directly into pre-drilled threaded holes (such as internal threads or wire thread inserts) in the connected parts through their own threads, or they form internal threads in softer materials through self-tapping, thereby achieving the functions of fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: These have standard mechanical threads (e.g., metric, imperial) and must be screwed into pre-machined internal threaded holes. The shank can be fully or partially threaded, used for precision assembly.

Self-Tapping Screws: These have the ability to drill, tap, and push, eliminating the need for pre-drilled internal threaded holes. Subcategories:

Ordinary Self-Tapping Screws: Used for plastics, wood, and thin metal sheets.

Self-Drilling Self-Tapping Screws: These have a drill tip that can penetrate steel plates, eliminating the need for pre-drilling and greatly improving efficiency.

Wood Screws: These have deep threads, large pitch, and sharp teeth, specifically designed for wood, providing strong locking force.

Set Screws: Used to fix the relative position of parts, preventing slippage or rotation. Various end shapes are available:

Tapered End: Provides high locking force, suitable for surfaces with high hardness.

Flat End: Large contact area, does not damage the surface.

Concave End/Cylindrical End: Used for positioning or pressing into holes on shafts.

Structural screws: a type of high-strength self-tapping screw that has undergone heat treatment and can be used to replace traditional bolts for steel structure connections, making installation faster.

Key Characteristics:

Compared to bolts, screws have the following distinct characteristics:

Primarily "tapping" or "screwing": Their core function is to directly form a threaded fit with the material being connected, rather than relying on a nut.

Relatively Frequent Disassembly: Commonly used for securing covers, panels, and components that require frequent assembly and disassembly.

Wide Size Range: From miniature precision screws used in eyeglasses and watches to large self-tapping screws used in building structures.

High Functional Integration: Many screws integrate multiple functions such as drilling, tapping, locking, and sealing (e.g., screws with washers, sealing screws).

Requirements on Substrate: Their load-bearing capacity largely depends on the strength of the substrate (e.g., plastics, wood, metal sheets).

Typical Application Areas:

Screws are ubiquitous, covering almost all industrial and daily life sectors:

Electronics and Appliances: Extensive use of miniature machine screws and self-tapping screws to secure housings, circuit boards, and internal components. Materials are mostly stainless steel or surface-treated carbon steel.

Machinery and Automation: Used for mounting and securing panels, covers, sensors, guide rails, clamps, etc., primarily hexagonal head screws or pan head screws.

Construction and Decoration:

Drywall Screws: Specifically used for connecting drywall to joists.

Structural Screws: Used for connecting light steel and wood structures.

Self-Drilling Screws: Used for securing color steel plates and purlins.

Automotive Industry: Extensive use of various self-tapping screws and special-function screws in car body interiors, wiring harness clips, electronic equipment, and decorative parts.

Furniture and Wood Products: Wood screws are the primary means of connecting wood and boards (such as particleboard).

Precision Instruments and Watches: Uses extremely precise miniature machine screws, requiring very high standards for materials and tolerances.

Aerospace: High-strength, lightweight, and corrosion-resistant titanium alloy or non-alloy special screws are widely used.

Xinghua Ruibang Stainless Steel Standard Parts Co., Ltd., established on June 16, 2016, is located in Dainan Town, Xinghua City, Jiangsu Province, China, known as the "Hometown of Stainless Steel." It is a professional manufacturer of standard and non-standard stainless steel fasteners, primarily using 201, 304, 316, 304L, 316LB8, B8M, duplex stainless steel, and other special materials.
