#6-32 bolts
Set Screws
Set Bolts
#8-32 Bolts
What is one advantage of using a standoff retainer?
It increases motor speed
It reduces battery consumption
It eliminates the need for sensors
It prevents standoffs from rotating during assembly
Which bolt type is best suited for motion systems requiring alignment and reduced friction?
Phillips head screws
Shoulder bolts
Locking bolts
#8-32 bolts
Why are locking screws useful in VEX robotics?
They increase gear speed
They are lighter than other screws
They prevent loosening due to vibration
They are easier to remove
Which of the following is a disadvantage of using screws that are too long for a given application?
They provide better grip
They may interfere with moving parts
They reduce vibration
They improve alignment
What feature of a 4-post nut retainer helps improve structural rigidity?
It adds weight to the frame
It allows nuts to rotate freely
It locks into square holes to prevent shifting
It connects directly to motors
What is the main purpose of a bearing flat in VEX robotics?
To hold nuts in place
To secure wires to the frame
To support rotating shafts and reduce friction
To increase battery life
Which type of bearing flat is designed to fit inside C-channels for compact builds?
Pillow block bearing
Low profile bearing flat
Standard bearing flat
Standoff retainer
How does a bearing flat improve a robot’s drivetrain?
By holding screws in place
By increasing motor speed
By reducing friction and keeping shafts aligned
By connecting sensors to wheels
When assembling a multi-layer structure, which combination is most effective for alignment and ease of assembly?
Phillips screws and zip ties
Shoulder screws and washers
Nut retainers and #8-32 screws
Locking screws and rubber bands
