Understanding Socket Head Cap Screw Weight
The weight of socket head cap screws is key to consider. It depends on the material, size, and grade. Knowing these factors helps figure out the grade of socket head cap screw, its proof strength, and the right grade for stainless steel screws.
The material used affects the screw’s weight. You can find them in steel, stainless steel, and alloy steel. Stainless steel screws are heavier because stainless steel is denser.
The screw’s size, like its diameter and length, also matters. Bigger screws are heavier because they have more material. It’s important to know how screw size relates to weight for the right choice.
The screw’s grade affects its weight too. Grade 8 or Grade 10.9 screws are stronger and heavier than Grade 5 or Grade 2. Knowing the proof strength and the right grade for your project helps pick the best screw.
Looking at the material, size, and grade helps you pick the right screw for your project. This knowledge is key for safe, reliable, and effective use of socket head cap screws.
Factors Affecting Socket Head Cap Screw Weight
The weight of socket head cap screws is key to consider. It depends on the material and size of the screw.
Material Composition
The type of material used in socket head cap screws affects their weight. Common materials are steel and stainless steel, each with different properties and weights.
- Steel screws are lighter, with Grade 5 (8.8) and Grade 8 (10.9) being popular. They balance strength with weight well.
- Stainless steel screws are heavier because of added elements. Grades 304 and 316 are chosen for resisting corrosion and lasting long.
Size and Dimensions
The size and dimensions of a screw also affect its weight. The length, diameter, and thread pitch all play a part in the fastener’s weight.
| Screw Diameter | Approximate Weight (Steel) | Approximate Weight (Stainless Steel) |
|---|---|---|
| 1/4 inch | 0.03 lbs (13.6 g) | 0.05 lbs (22.7 g) |
| 3/8 inch | 0.08 lbs (36.3 g) | 0.12 lbs (54.4 g) |
| 1/2 inch | 0.16 lbs (72.6 g) | 0.24 lbs (108.9 g) |
Knowing how material and size affect the weight of socket head cap screws helps you choose the right one for your needs.
Socket Head Cap Screw Weight Standards
Understanding the weight standards of socket head cap screws is key. These standards help pick the right fasteners for different jobs. Let’s look at what the markings on these screws mean for their weight and strength.
The “class” rating is a common way to tell what a socket head cap screw can handle. For example, a “10.9” screw is strong and has certain weight and strength levels.
| Rating | Tensile Strength (PSI) | Proof Strength (PSI) | Hardness (Rockwell C) |
|---|---|---|---|
| 5.8 | 85,000 | 58,000 | 22-32 |
| 8.8 | 120,000 | 88,000 | 31-37 |
| 10.9 | 150,000 | 109,000 | 33-39 |
The 10.9 rating on a bolt doesn’t mean it’s a “grade 8” fastener. The two systems have different rules. It’s important to know the strength and weight of a 10.9 class screw compared to others.
Learning about these standards helps you pick the right socket head cap screws. This is true whether you need something for heavy loads or something light.

Socket Head Cap Screw Weight
Socket head cap screws come in different weights. Their strength and weight depend on the material, size, and grade. Knowing the weight helps with planning and calculating loads.
The weight of a socket head cap screw varies from a few grams to several pounds. The material affects its weight. Stainless steel and alloy steel screws are heavier than those made from aluminum or brass.
The screw’s size and dimensions also play a role in its weight. Longer and thicker screws weigh more. The class or grade of the screw, which shows its strength, can also affect the weight. Higher-grade screws are usually heavier.
| Screw Size | Material | Class/Grade | Approximate Weight (grams) |
|---|---|---|---|
| #10 x 1-inch | Stainless Steel | 18-8 | 5.5 |
| 1/4-20 x 2-inch | Alloy Steel | Grade 5 | 14.2 |
| 3/8-16 x 3-inch | Aluminum | N/A | 8.6 |
| 1/2-13 x 4-inch | Brass | N/A | 34.4 |
Choosing the right socket head cap screw involves more than just looking at its weight. You also need to think about the application, load-bearing capacity, and compatibility with the materials you’re working with.
Choosing the Right Socket Head Cap Screw Weight
When picking a socket head cap screw, think about what your project needs. The screw’s weight affects its performance and your project’s reliability. Knowing what makes a screw heavy or light helps you pick the best one for your project.
Application Requirements
First, look at what your project needs. Think about these things:
- The load-bearing capacity needed for your project
- The environment in which the screw will be used (e.g., corrosive, high-temperature, or high-vibration conditions)
- The space constraints and accessibility of the installation area
- Any unique installation or performance needs, such as the need for easy disassembly or resistance to loosening
Load-bearing Capacity
The weight of a socket head cap screw tells you how much it can hold. Heavy screws are stronger and can handle more stress. They’re good for tough applications. Lighter screws are better for less demanding tasks or where you need to save weight.
When looking at socket head cap screw weight, don’t forget about the material and size. These can affect how strong and long-lasting the screw is.
“Choosing the right socket head cap screw weight can ensure the safety and reliability of your project.”
Socket Head Cap Screw Weight vs. Other Fasteners
Choosing the right fastener for your project is key. It’s important to know the weight and strength differences between socket head cap screws and other fasteners like hex head bolts. Questions like is grade 12.9 stronger than grade 8? or which bolt is stronger, grade 8 or A490? matter a lot.
Socket head cap screws are popular for their secure fit and good looks. But, they might not always be the best choice. In some cases, when when not to use grade 8 bolts? is a question, other fasteners work better.
| Fastener Type | Typical Tensile Strength (psi) | Weight Comparison |
|---|---|---|
| Grade 8 Hex Head Bolt | 120,000 | Lighter than grade 12.9 socket head cap screws |
| Grade 12.9 Socket Head Cap Screw | 174,000 | Heavier than grade 8 hex head bolts |
| A490 High-Strength Structural Bolt | 150,000 | Typically heavier than grade 8 hex head bolts |
The table shows the main differences in strength and weight among these fasteners. Grade 12.9 socket head cap screws are stronger than grade 8 bolts but heavier. A490 bolts are a good middle ground, balancing strength and weight well.
Choosing between socket head cap screws, hex head bolts, or other fasteners depends on your project’s needs. Consider the load, weight limits, and design. This way, you can pick the best fastener for your project.
