A2 premium stainless steel button head bolts, fully threaded from tip to head with socket hex drive. Supplied as a set with matching nuts and washers for immediate use in indoor projects.


Long-lasting corrosion resistance – with A2 premium stainless steel

A2 stainless steel is specified for indoor use because it is manufactured to resist corrosion and maintain surface integrity. The material choice reduces the risk of rust where moisture or food-contact are factors.

Reliable performance in kitchens, catering areas and interior fittings helps avoid frequent replacement. Acceptable longevity makes the fastenings suitable for projects where appearance and durability matter.

Secure, even clamping – with fully threaded shafts

Fully threaded bolts run thread from tip to head, allowing nut engagement along the entire length of the shaft. Full threading spreads load more evenly across the joint compared with partial-thread fasteners.

Consistent grip reduces loosening under vibration and helps maintain structural integrity in assemblies. Ideal for joins that require a tight, uniform clamp such as shelving supports and handrail fixings.

Quick installation – with button socket hex head and included hardware

Socket hex button head design accepts a hex key for controlled tightening while the low-profile head reduces snagging. Each set includes matching nuts and washers so no separate fasteners are required.

Faster assembly and fewer trips to the parts box make small jobs simpler and neater. The low-profile head suits visible interior fittings where a flush, tidy finish is preferred.

✨ The 4 Key Reasons for Universal Hardware Button Head Bolts
  1. Fully threaded shaft - Ensures even clamp and reduces risk of joint failure under vibration
  2. Socket hex button head - Low-profile finish fits neat interior fixtures without protruding
  3. Includes nuts and washers - Ready to install straight from the pack for common repairs
  4. Secure packaging - Arrives intact and protected, reducing risk of damaged fasteners
