# How much weight can a steel bolt hold?

## How much weight can a steel bolt hold?

For example, an eye bolt with a 1/4 inch shank can typically hold up to 600 pounds at a straight pull (no angle). However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the “straight pull” weight capacity).

How do you calculate bolt load capacity?

The tensile load a fastener can withstand is determined by the formula P = St x As. To find the tensile strength of a particular bolt, you will need to refer to Mechanical Properties of Externally Threaded Fasteners chart in the Fastenal Technical Reference Guide.

### How do you figure out what size bolts I need?

How to Measure the Size of a Bolt

1. Step 1: Measure the shank’s diameter. The shaft of the bolt is called the shank, and its diameter is the first dimension used to describe a bolt size.
2. Step 2: Determine the thread pitch.
3. Step 3: Measure the length of the shank.
4. Step 6: Measure the length of the threaded portion of the bolt.

How much force can a 1/2 bolt hold?

2 5
7/16 5850 9050
1/2 7800 12100
9/16 10000 15500

## Are stainless bolts stronger than Grade 8?

Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.

Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head.

### How much weight will a 3/8 bolt hold?

A 3/8-inch bolt of this type is rated to 7,000 pounds in 6,000 psi concrete (basically granite) and 4,000 pounds in 2,000 psi concrete (hard sandstone). This is roughly the breaking strength range of carabiners and much higher than any rope’s maximum possible impact force.

How much shear force can a bolt take?

The Industrial Fastener Institute (Inch Fastener Standards, 7th ed. 2003. B-8) states that shear strength is approximately 60% of the minimum tensile strength. “As an empirical guide, shear strengths of carbon steel fasteners may be assumed to be approximately 60 percent of their specified minimum tensile strengths.

## What are standard bolt sizes?

US Standard Thread Length for Bolts

Bolt Diameter Standard Thread Length (in.) *
Bolts 6 inches and shorter Bolts longer than 6 inches
5/8″ 1-1/2″ 1-3/4″
3/4″ 1-3/4″ 2″
7/8″ 2″ 2-1/4″

How much bigger should a hole be than a bolt?

Select a drill bit 1/32 inch larger than the bolt diameter for a tight fit hole or a drill bit 1/16 inch greater than the bolt diameter for a loose fitting hole.

### What grade bolt has the highest shear strength?

12.9 Bolt Shear Capacity

• 12.9 Bolts. A 12.9 bolt is one of the highest grade of bolts produced. Known for their high tensile strength, they are built with both hex and Torx heads and are available in zinc or chrome finishes.
• 12.9 Shear Strength. The minimum tensile strength of a 12.9 bolt is 1220 MPa.

How much weight can a 10 24 bolt hold?

What are the dimensions of a steel bolt?

Body Diameter – There may be a reasonable swell or fin under the head or die seam on the body not to exceed the basic bolt diameter by the following: 0.030″ for sizes up to 1/2″ 0.050″ for sizes 5/8″ and 3/4″

### How big is a 150 lb stud bolt?

What should I look for on a stud bolt chart?

Below is ASME B16.5 150#, 300#, 600# Stud Bolt Flange Chart information that can assist engineers and pipe fitters with calculating the number of fasteners associated according to flange size. This is for informational purposes only. Novices should first make sure that they are looking at the appropriate flange class / schedule “poundage”.
