What to know before buying

The listing gives only an overall assortment count and does not provide a per-size or per-component breakdown. Its M8 x 1.25 thread-size, 8-millimeter diameter, and hex-head details are specific to the listed item details and do not establish thread pitches or dimensions for every size in the assortment. The stated size range of 12–30 mm appears in the title, but the supplied details do not give a length-by-size inventory. Confirm the fastener mix and lengths against the job before purchase. The corrosion and weather-resistance statements are manufacturer claims, not independently verified performance.
