Configurable Screws

LoonyLib features a number of useful bolt types not found in the OnShape FTC Robotics Parts Users library. These types include:

All these screws are generated from a single doc, called Screws (configurable). It also includes standard socket head, low head, and button head screws to make switching between types easy. You can simply edit the configuration to change the head type, thread size, and length in context.

You can purchase the M3-M5 countersunk bolts from McMaster-Carr or Monster Bolts:

The metric shoulder bolts can be purchased from WDS Components:

The low profile Phillips bolts can be purchased from MiSUMi:

Lead screws can be purchased from many COTS vendors, such as goBILDA.

Screws (configurable)

This doc makes it simple to add bolts of all common types to your designs. It includes configurations for head type, thread size, length, and finish. The threads are toggleable for performance. Length is adjustable via a variable input so making any length bolt is easy. We've created a lookup table of available screw sizes that can be purchased from various vendors to make double checking availability easy.

Metric Shoulder Bolts (configurable)

Shoulder bolts are useful in places where a deadaxle is too bulky or expensive. They are easy to thread through multiple plates and run spinning components on. They can also be used to add reinforcement to wide structures. 

This doc comes in M5 and M6 variants, which are easy to use with common metric bearings. They are compatible with all other threaded objects with matching threads. These models also come with a mate connector at the bottom of the head. All lengths can be purchased from WDS Components.

Lead Screw (configurable)

Lead screws are a simple and inexpensive way to create linear motion. They come in many sizes, but the most common for FTC is goBILDA's 8mm diameter. This model lets you customize the diameter, thread pitch, and length of the lead screw to fit your specific needs. It comes with mate connectors pre-applied to each end for easy attachment.
