Explore Custom Fasteners Weight Chart in MM and KG: Sizes, Types & Weight Guide
Author : pipex ai | Published On : 26 Aug 2026
Custom fasteners are widely used across construction, engineering, automotive, fabrication, machinery, and industrial applications where standard fastening solutions may not meet specific project requirements. Selecting the right fastener involves more than checking its size or thread type. Weight is also an important factor when estimating material requirements, transportation costs, packaging quantities, and overall project requirements.
A custom fastener weight chart in mm and kg provides a convenient reference for understanding the approximate weight of fasteners according to their diameter, length, type, and material. This information can help buyers, engineers, fabricators, and suppliers make faster decisions when preparing quotations or planning bulk requirements.
Understanding Custom Fastener Weight
The weight of a fastener generally depends on its size, length, material, shape, and design. For example, increasing the diameter or length of a bolt normally increases its overall weight. Similarly, fasteners manufactured from different materials can have different weights even when their dimensions are similar.
The weight chart provided above includes commonly used metric sizes such as M5, M6, M8, M10, M12, M16, M20, M24, M27, and M30. It provides approximate weights for different lengths, making it easier to compare requirements before placing an order.
For custom-made fasteners, the actual weight may vary depending on the component design and manufacturing specifications. Therefore, chart values should generally be treated as reference figures rather than final certified weights.

Why Use a Fasteners Weight Chart?
A fastener weight chart can be useful for several stages of industrial purchasing and project planning. It helps with:
-
Material estimation: Calculate approximate quantities required for large projects.
-
Quotation preparation: Estimate product weight for commercial calculations.
-
Transportation planning: Determine approximate shipment weight and logistics requirements.
-
Packaging: Plan suitable quantities and packaging for bulk orders.
-
Inventory management: Compare stock requirements based on fastener size and weight.
-
Product selection: Review different sizes before finalising specifications.
For manufacturers and buyers dealing with bulk quantities, even a small difference in the weight of individual components can become significant when thousands of pieces are ordered.
Custom Fasteners by Type and Material
Custom fasteners are available in various forms, including hex bolts, hex nuts, flat washers, socket head cap screws, threaded rods, studs, and rivets. Each type has its own dimensional and weight characteristics.
Material selection is equally important. Common options include mild steel, carbon steel, alloy steel, stainless steel, and aluminium. The required material depends on factors such as mechanical strength, corrosion resistance, operating environment, temperature, and application requirements.
The second table provides reference values for different fastener types, sizes, lengths, materials, and approximate weight per 100 pieces. This makes it useful for comparing common fastener configurations in one place.

How to Calculate Fastener Weight
For customised requirements, fastener weight can be estimated from the component's dimensions and material density. However, complex shapes, threads, head designs, recesses, and manufacturing tolerances can affect the final weight.
For accurate purchasing and production, buyers should provide the manufacturer or supplier with complete specifications, including fastener type, diameter, length, thread specification, material grade, finish, quantity, and applicable standard.
Using a reliable custom fasteners weight chart in mm and kg can simplify product comparison, quantity planning, and preliminary cost estimation. For exact requirements, the final weight should always be confirmed according to the approved product drawing and specifications.
