What kind of holes are used for bolting?
• Bolts are installed in one of four types of holes (see table above) • Standard holes can be used anywhere • Oversized holes may only be used in slip‐criticalconnections •Short‐slotted holes are used with the slot perpendicular to the direction of stress •Long‐slotted holes are primarilyused when connecting to existing structures
What is the standard length of a bolt?
Metric Standard Thread Length for Bolts. Bolt Diameter. (mm) Standard Thread Length (mm) *. Bolts 125mm and shorter. Bolts longer than 125mm. 3. 12. -.
What are the holes for wall mount brackets?
The wall mount hole pattern on some models may conform to the VESA Mount Standard, but the number and depth of the screw holes do not. Note: Some models come with an AC power adapter. The length of power cord and the size of the AC power adapter is listed for some models.
What are the different types of structural bolting?
1. Joints that are subject to fatigue load with reversal of the loading direction (not applicable to wind bracing) 2. Joints that utilize oversized holes 3. Joints that utilize slotted holes, except those with applied load approximately perpendicular to the direction of the long dimension of the slot 4.
What’s the standard size of a bolt hole?
Standard hole sizes for bolts are made 1/16-in. larger in diameter than the nominal size of the fastener body. This provides a certain amount of play in the holes, which compensates for small misalignment’s in hole location or assembly, and aids in the shop and field entry of fasteners.
What is the diameter of a bolt circle?
Hole diameter: The diameter of the holes that are equally distributed around the bolt circle diameter. Bolt circle diameter: the diameter of the circle on which the holes will be evenly distributed. Start angle: The 0° angle is to the right in the “X” axis and aligned with the center of the bolt circle in the “Y” axis.
Why are standard holes used in bolted connections?
This provides a certain amount of play in the holes, which compensates for small misalignment’s in hole location or assembly, and aids in the shop and field entry of fasteners. In the absence of approval by the engineer for use of other hole types, standard holes shall be used in high strength bolted connections.
What is the clamped length of a bolt?
It is also called “grip length” as the total thickness of clamped parts under compression. To optimise a bolted joint, it is recommended to design the clamped length to at least 3 or 5 times the bolt diameter.
