Help with Lead Screws and ACME Screws specifications:

Screw Type
   Screw Type       
   Your choices are...         
   ACME Screw       ACME screws have a very specific thread geometry that directly contacts the nut and provides linear motion through direct sliding friction between nut and lead screw.  ACME threads are square-topped. 
   Lead Screw       Lead screws drive a nut in linear motion via direct contact with the nut.  Lead screws often incorporate proprietary screw and nut geometry and materials and can be configured in zero-backlash arrangements.

   Component Type       
   Your choices are...         
   Screw Assembly       Product consists of a nut and screw assembly. 
   Nut Only       Product consists of a nut only.  Screw must be purchased separately. 
   Screw Only       Product consists of a screw only.  Nut must be purchased separately.

Manufacturing Process
   Manufacturing Process       
   Your choices are...         
   Rolled Thread       Rolled screws are cold rolled from a blank. Typically, this produces a screw with a .004 inch per foot accuracy. 
   Milled Thread       Milled screws are made on a milling machine using a cutter with an Acme form. Typically, this produces a screw with a .002 inch per foot accuracy. 
   Ground Thread       Ground screws are made on a grinding wheel with an Acme form. Typically, this produces a screw with .0005 inch per foot lead accuracy. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Physical Specifications
   Length:         
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   O.D Screw Diameter:       The largest diameter value of the screw. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Screw Lead:       The axial distance a screw travels during one revolution, measured in inch/turn or mm/turn. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Screw Lead Accuracy:         
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Dynamic Load Rating:       The load that can be sustained while the assembly is moving. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Static Load Capacity:       The load that can be sustained, measured while the load is stationary. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Design Features
   Design Features       
   Your choices are...         
   Lubrication Port         
   Left Hand Thread       The direction of the threads on the screw shaft causing the ball nut to travel away from the end viewed when rotated counter-clockwise. 
   Right Hand Thread       The direction of the threads on the screw shaft causing the ball nut to travel away from the end viewed when rotated clockwise. 
   Twin Lead       Lead is the axial distance a screw travels during one revolution. Twin leads are useful in opposing dual motion using a single drive system. This design features both the Left and Right Hand threads. 
   Zero Backlash Design       Backlash is the axial free motion between the nut and screw. It is a measure of the stiffness of the assembly. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
