About this fastener assembly
This is a fastener assembly in 10B21 Carbon Steel, at strength class Grade 10.9, supplied nickel plated, with an M8 thread and a 16 mm length. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A fastener assembly arrives with the washer already on the screw, which removes one loose part from the assembly line and one from the parts bin. Used on volume assembly work — appliances, electronics, furniture and automotive trim — where handling time per fixing matters.
Nickel plating gives a bright, hard, decorative finish with useful corrosion resistance. Common on furniture and visible hardware.
M8 is a metric thread with an 8 mm nominal diameter and a coarse pitch of 1.25 mm (ISO 261). A standard hex head takes a 13 mm spanner across the flats.
Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
