How long is the hexagonal bolt connection used for aluminum profile trolleys?
Publish Time: 2024-11-04
The length of the hexagonal bolt connection used for the aluminum profile trolley depends on the specific profile specifications selected. To illustrate this, we assume that a 4040 aluminum profile is used, and its hexagon socket bolt specification is M8*45. The selection of this specification is based on the following factors:Influence of profile specifications: The cross-sectional dimensions of the aluminum profile directly affect the required length of the hexagon socket bolt. For example, for a 4040 aluminum profile (width of 40 mm), the bolt length must adapt to the size of the profile while ensuring a solid connection.Calculation of bolt length:Determine the profile size: First, understand the cross-sectional dimensions of the aluminum profile, which determines the basic range of bolt diameter and length.Consider the connection strength: To ensure a solid connection between the two profiles, a certain allowance is required for the bolt length. This allowance usually depends on the size of the profile and the connection method.Calculate the bolt length: Bolt length = profile cross-sectional dimensions (minus groove depth, etc.) + connection allowance + nut tightening length. For example, for 4040 profiles and cross-drilling connection methods, in addition to the 40mm size of the profile and the extra length required for nut tightening, a 5mm margin may be required for connecting to the end face of another profile.Common bolt length examples: For 4040 aluminum profiles, common hexagon socket bolt lengths may include M8*45. Among them, M8 represents the 8mm bolt diameter, and 45 represents the total bolt length (including threaded and non-threaded parts). Please note that the specific bolt length may vary depending on the profile size, connection method, required strength, and manufacturer differences.Other considerations for half-round head bolts: When using half-round head bolts, the specifications do not necessarily match those of hexagon socket bolts due to their different connection structures. Hexagon bolts pass through the profile, while half-round bolts are tapped to the end face of the profile, slide into the groove, and tighten through the through hole in a fixed position. This combination prevents cross-blocking of bolts in three-profile connections.Bolt length customization: Both types of bolts can be customized in length, but common depths include 6mm, 10mm, 8mm, 12mm, 16mm, and even 45mm. Bolts are usually required for frame assembly.Other important considerations:Select the appropriate bolt specifications: In addition to length, select the appropriate bolt diameter and thread specifications to ensure compatibility with profiles and connectors.Follow manufacturer recommendations: When purchasing and using hex socket bolts, follow the manufacturer's safety and reliability guidelines.Regular inspection and maintenance: For aluminum profile trolleys and other equipment that use hex socket bolts, perform regular inspections and maintenance to ensure the firmness and safety of the connection.The length of the aluminum profile trolley hex bolt is determined by the profile specifications. There are many factors to consider when selecting. Selecting the appropriate bolt specifications and regular maintenance are essential to ensure the structural integrity and safety of the trolley.
