Product identity

The Kerr Lakeside 50C800KCS .5 - 13 x 8 in. Socket Cap Screw is a Grade 8 alloy steel fastener with a black oxide finish. It uses a 3/8 in. socket drive and features a 1/2 in.-13 thread that is partially threaded along its 8 in. length. The pack contains 10 pieces for maintenance or assembly tasks.

Interface limits

The socket drive requires a matching 3/8 in. hex bit or wrench for installation and removal. The inch-based thread follows ANSI B 18.3 dimensional standards and will only engage correctly with compatible 1/2 in.-13 internal threads. The partially threaded shank means the unthreaded portion cannot accept a nut.

Setup checks

Verify that the mating hole or nut uses a 1/2 in.-13 thread pitch and that the available depth accommodates at least the 1 1/2 in. minimum thread length. Confirm the 3/8 in. socket drive tool is on hand and that the 8 in. overall length fits within the assembly space. The black oxide finish provides limited corrosion resistance.

Questions about this item

Should I pick the 10-piece pack or a larger quantity for my project?

The listing is a 10-piece small pack of 1/2-13 x 8 in. Grade 8 socket cap screws; order multiple packs if you need more than ten fasteners.

How does the Grade 8 rating affect strength in a real assembly?

Grade 8 alloy steel with black oxide finish provides high tensile strength for demanding clamping loads in inch-series threaded holes.

What does the ANSI B 18.3 standard mean for fit and torque limits?

ANSI B 18.3 defines the 3/8 in. socket drive, 0.5 in. head height and 0.75 in. head diameter, ensuring standard tool engagement and torque capacity.
