Socket Shoulder Screws

Socket Shoulder Screws
Threads: ANSI B 1.13 M, ISO 262Similar Specifications: ANSI B18.3.3M, ISO 7379, DIN 9841.Shoulder screws have an undercut portion between the thread and shoulder, allowing a close fit. Theyre used for a wide range of punch and die operations, such as the location and retention of stripper plates, and act as a guide in blanking and forming presses.Other applications for shoulder screws include: bearing pins for swing arms, links and levers, shafts for cam rolls and other rotating parts, pivots, and stud bolts. Shoulder screws are sometimes referred to as stripper bolts, resulting from their use with stripper plates and springs.

Features:
  • Material: ASTM A574M alloy steel
  • Hardness: Rc 36-43
  • Tensile Stress: 1100 MPa based on minimum thread neck area (J min.).
  • Shear Stress: 660 MPa
  • Concentricity: Body to head O.D. within 0.15 TIR when checked in a Vblock. Body to thread pitch diameter within 0.1 TIR when checked at a distance of 5.0 C from the shoulder at the threaded end.Squareness, concentricity, parallelism, and bow of body to thread pitchdiameter shall be within 0.05 TIR per centimeter of body length with a maximum of 0.5 when seated against the shoulder in a threaded bushing and checked on the body at a distance of 2.5 B from the underside of the head.
  • Squareness: The bearing surface of the head shall be perpendicular tothe axis of the body within a maximum deviation of 2.
  • Thread Class: 4g 6g

Socket Head Shoulder Bolts are purposed for use in punch or die applications in the placing of stripper plates. Socket Head Shoulder Bolts are a precision made product with a polished shoulder, manufactured to precise measurements and tolerances

Socket Head Shoulder Bolts can be guides for banking and forming presses.

Socket Shoulder Screws are available in metric sizes from M5 to M12 and are commonly used as standard fasteners on many applications.

The head of the cap screw has a hexagonal recessed drive this can be adjusted using a Hex driver or Allen key.

Alternative names for socket shoulder screws are: Hex Shoulder Socket Screws, socket head shoulder screws, Shoulder hex screws, Metric shoulder screws.

  • Description Fully threaded, headless screw with a hexagonal drive at one end and a cup-shaped indentation at the other.
  • Fully-threaded, headless screw with a hex drive at one end and a protruding tip with a flat surface at the opposing end. Posseses an oval-shaped point on the end opposing the flush hex drive.
  • Posseses a flat surface at the end opposing the hexagoal drive.   Has a shart conical-shaped point at the opposite end from the hexagonal drive.
  • Applications/ Advantages Most used style Designed for fast, permanent and semi-permanent location of parts on shafts with a hardness differential of 10-15 Rockwell C points and where cutting in of the cup edge on the shaft is acceptable.
  •  For permanent setting - often used instead of a dowel pin. The point should closely fit the diameter of the drilled hole, or alternatively, against the flat. The preferred style for frequent re-set on soft or hard shafts with minimum deforming. Often used for permanent setting on shafts that are spotted, splined or grooved, and for applications where the point meets the shaft on an angle. Sometimes sub

  • Heat Treatment Set screws should be heat treated via oil quenching from above the transformation temperature and then tempered at a temperature that is condusive to meeting the hardness requirements.
  • Hardness Rockwell C45 - 53
  • Torsional Strength Socket set screws of sufficient length should be tested to determine if that can withstand the application of the test torque outlined in the above table without evidence of the socket reaming or the screw bursting.
  • Finish Black Thermal Finish

the cup point is the most comonly used set screw. It has a cup-shaped indentation on one end. The cup point is used for quick, permanent and semi-permanent part assemblys and where the cutting in of the cup point edge is acceptable.

Socket Head Cap Screw

Socket Head Cap Screw
Low Head Socket Cap Screws are designed to be used in applications where head height clearance is a problem. Low Head Socket Head Cap Screws cannot be preloaded as high as a standard socket head cap screw because of their reduced head height and smaller socket size.Low Head Socket Head Cap Screws are manufactured from High Strength Alloy Steel and have a Black Oxide finish.
