The fasteners used with hex tools are available in an incredibly wide range of sizes and strengths, and with features unique to the various types. Hex fasteners are available for nearly any assembly project where critical factors will not permit the use of lower quality alternative fasteners.
Common Screw Types:
Uses: Applications where maximum strength is required. Used as protruding or counter bored.
Variations: A range of choices available for special use applications:
Uses: Applications where parts are not thick enough to be counterbored or clearance is too limited to use full height cap screw.
Uses Fastening parts on a shaft – pulleys, gears, collars, etc.
Variations: Options include:
Strength: An assembly with three socket head cap screws has more strength than one with five equivalent hex head screws.
Savings: Using fewer screws means labor savings associated with drilling fewer holes and installing fewer screws.
Tensile, yield, and shear strength: An assembly done with a cap screw has over 50% more tensile strength, 100% better yield strength, and over 30% more shear strength.
Clearance: Socket head cap screws have no side clearance restrictions associated with the sockets and wrenches used with hex head screws. As a result, they can be placed closer together, and used in applications where associated side clearance would make hex head screws impractical. When overhead clearance is an issue, or a flush profile is necessary, the low head and flat head versions are a good solution.
