Metallics JSS51658 – Frequently Asked Questions
1) Can I use the JSS51658 as a replacement set screw in an electrical lug or connector?
That is what it is stocked for. Metallics catalogs the JSS51658 as an electrical fastener, and a 5/16-18 x 5/8 cup point socket set screw is the common replacement size for mechanical lugs, split-bolt and set-screw connectors, and busbar collars. Match the thread to the tapped hole in your lug before ordering, since 1/4-20 and 3/8-16 are also widely used on that style of connector.
2) Is the JSS51658 set screw a cup point or a flat point?
Cup point. The JSS51658 has a cup (concave, ring-edged) tip that bites into the mating surface for a high-holding grip, which is the usual choice for locking a conductor, collar, or shaft in place. If you need a non-marring hold on a finished shaft or want repeated loosening without chewing up the surface, a flat or nylon-tip set screw is the better pick instead.
3) What driver do I need for the Metallics JSS51658 set screw?
It is a socket (internal hex) set screw, so it takes an Allen key or hex bit driver, not a slotted or Phillips screwdriver. There is no external head to grip, which is also why it seats flush or below the surface of a lug or collar.
4) How many screws come in the Metallics JSS51658 pack?
Each jar holds 100 pieces of the 5/16-18 x 5/8 socket set screw. The jar pack is aimed at shop and service-truck stocking, where you are pulling a few at a time for lug and connector work rather than buying per piece.
5) Are these Metallics set screws steel or stainless?
Steel. The JSS51658 is a steel socket set screw, so plan on a dry, indoor, or enclosed location. For wet, outdoor, or corrosive settings, specify a stainless set screw of the same 5/16-18 x 5/8 size instead.
6) What is the Metallics part number to order for a 5/16-18 x 5/8 cup point socket set screw?
Order Metallics JSS51658. That is the manufacturer part number for the 5/16-18 x 5/8 inch steel cup point socket set screw supplied in a 100 piece jar, and it is the only configuration under that number.
