- What does a combination Phillips slotted drive mean?
- The head has a cross recess plus a slot, so either a Phillips or a flathead screwdriver will turn it. It is handy when you do not want to switch tools.
- Are these for wood or metal?
- They are machine screws, so they thread into tapped metal, nuts or threaded inserts. For wood you would normally use wood screws.
- What size and length are they?
- The pack name does not state the thread diameter or length, so check the product specs before ordering. Machine screw sizes are given as diameter by length, such as #8-32 x 1 inch.
- Do they come with nuts or washers?
- The pack is listed as 100 screws only. Nuts and washers are usually sold separately.
- Will the silver finish rust?
- They are steel with a silver finish, likely zinc plated. That resists light moisture but is not a substitute for stainless steel outdoors.
- Where is the Zoro Select Combination Phillips Slotted Round Machine Screw 100 PK cheapest?
- At Newegg, for $154.99, as of our latest check.
