No ragged chips are in the socket bottom to prevent the full leverage of the hex key from being used. Sockets are accurately centered in the screw head and are formed with clean edges without burrs. Accurately Formed Heads: Screws have the standard 82 degree angle under the head.

Costly slips of the driving tool are avoided, along with possible damage both to the work and the screw.

Non-Slip Driving: With the close-fitting, internally engaging hex key, power is transmitted for extra firm setups without loss through side play, reaming or slipping.

Roller threader, headers, overhead rails for chain hoist.

Fastening where maximum flush and sidewall contact is required.

Ideal for thin sections where heads cannot protrude.

These heavy-duty screws are especially well suited to fastening thin plates, strips, moldings, and sheet metal parts where the advantages of maximum head contact, flush surfaces and nonslip wrenching action are combined.
