UNF Hex Head Bolts | Imperial Fine Thread

LAZER

View all Brands

We supply UNF hex head bolts manufactured to Unified National Fine thread specifications. UNF bolts feature a finer thread pitch than UNC, providing improved clamping precision and increased resistance to loosening under vibration.

Commonly used in automotive, machinery and precision engineering applications, UNF hex head bolts are ideal where a finer adjustment and higher tensile stress area are required.

Available in a range of UNF imperial sizes and strength grades including high tensile and stainless steel options, our bolts provide reliable fastening for industrial and workshop use.

Bulk quantities available with competitive trade pricing and fast UK delivery.
