Designed for frequent re-setting or re-locating on hard steel shafts and where minimal damage is shafts is essential.
Ground flats on the shaft improves the contacts. : Designed for permanent setting on soft or hardened shafts.
Deep penetration gives this style of screw the highest torsional and axial holding power.
Can be used as a hangar or pivot.
For shafts of Rockwell hardness C15 or more, spot point half
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.
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.
Material : Made from alloy steel with a chemical composition of: 0.28 to 0.50% Carbon, 0.040% (max) Phosphorus, and 0.045% (max) Sulfer. Also, chromium, nickel, molybdenum or vanadium should be present in a quantity sufficient to meet the strength requirements outli
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.
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.
Hardness : Rockwell C45 - 53
Description : Fully threaded, headless screw with a hexagonal drive at one end and a cup-shaped indentation at the other.
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.
The popularity of Flat Head Cap Screws grows because of its positive, hex-socket wrenching feature, use of heat-treated alloy steel and precision Class 3 fit threads. Non-Slip Driving: With the close-fitting, internally engaging hex key, power is...
